Although the observational importance of the spectrum at high-energy side has been pointed out, the Emulsion Chamber experiments were the only one which observed the electron spectrum up to TeV region. Successive experiments of cosmic-ray electrons using emulsion chambers since 1977 have yielded about 10 times exposures in total as large as those of our previous experiments (Nishimura. J. et al, 1980). Our total exposure is now about 6.6x10^5m^2・s・sr, including those before 1977, which is one or two order magnitude larger than those of other experiments. This enabled us for the first time to observe the electron spectrum in TeV region. We present here the electron spectrum in the energy range 30GeV to 3TeV at the top of the atmosphere, which is expressed as : Je(E) = (1.42+/-0.26) x 10^-4(100GeV/E)^3.26+/-0.11/m^2・s・sr・GeV. This is essentially the same as our previous results in the low energy side. We also present the atmospheric gamma-ray spectrum at the balloon altitude that was obtained in the course of the data analysis of electrons. The gamma-ray spectrum normalized at 4g/cm^2 altitude is well represented by a single power law spectrum : Jg(W)=(1.11+/-0.13) x 10^-4(100GeV/W)^2.74+/-0.06/m^2・s・sr・GeV, in the range of 30GeV to 10TeV. We can deduce the flux of primary protons in the energy range of 300GeV to 50TeV from this gamma ray data, if we assume a certain model of hadronic interactions. Base on these data, we discussed the origin and propagation of the observed electrons in terms of the diffusion model, and possible spectral fluctuations in the TeV region due to the contribution of a small number of nearby sources.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0200100000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"青山学院大学理工学部"},{"subitem_text_value":"神奈川県立衛生短期大学"},{"subitem_text_value":"神奈川大学工学部"},{"subitem_text_value":"神奈川大学工学部"},{"subitem_text_value":"神奈川大学工学部"},{"subitem_text_value":"神奈川大学工学部"},{"subitem_text_value":"神奈川県立衛生短期大学"},{"subitem_text_value":"青森大学工学部"},{"subitem_text_value":"名古屋大学太陽環境研究所"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"Dep. of Physics, Universiity of Washington, Seattle, USA."},{"subitem_text_value":"Dep. of Physics, University of Washington, Seattle, USA."}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"College of Science and Engineering, Aoyama Gakuin University"},{"subitem_text_language":"en","subitem_text_value":"Kanagawa Prefectural College Nursing Medical Technology Public Health"},{"subitem_text_language":"en","subitem_text_value":"Faculty of Engineering, Kanagawa University"},{"subitem_text_language":"en","subitem_text_value":"Faculty of Engineering, Kanagawa University"},{"subitem_text_language":"en","subitem_text_value":"Faculty of Engineering, Kanagawa University"},{"subitem_text_language":"en","subitem_text_value":"Faculty of Engineering, Kanagawa University"},{"subitem_text_language":"en","subitem_text_value":"Kanagawa Prefectural College Nursing Medical Technology Public Health"},{"subitem_text_language":"en","subitem_text_value":"Aomori University"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science (ISAS)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science (ISAS)"},{"subitem_text_language":"en","subitem_text_value":"Dep. of Physics, Universiity of Washington, Seattle, USA."},{"subitem_text_language":"en","subitem_text_value":"Dep. of Physics, University of Washington, Seattle, USA."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小林, 正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"古森, 良志子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"吉田, 健二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"白井, 達也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"立山, 暢人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平良, 俊雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"会津, 英子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤井, 正美"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"湯田, 利典"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山上, 隆正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"西村, 純"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"J., J.
