 note = {The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido Japan, The X-ray emission from the supernova remnant N23 are studied using the X-ray Imaging Spectrometer (XIS) onboard Suzaku. Owing to superior energy resolution of the XIS, we obtained a H-like and He-like Kalpha emission line spectrum of Oxygen with unprecedentedly high quality. As a result, we identified a new thin thermal spectra component which can be represented with Non-Equilibrium Ionization model with a temperature approximately0.2 keV, as well as that with a temperature  of approximately0.5 keV so far as known. This alters the estimate of the ionization timescale n(sub e)t from approximately 10(exp 11) cm(exp -3)s to  approximately 10(exp 13)cm(exp -3)s, thereby identifying N23 as an old SNR, rather than a young SNR(approximately3800yr) as believed so far., Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, 資料番号: AA0064574049, レポート番号: JAXA-SP-09-008E},
