 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 spectrum of the Galactic supernova remnant (SNR) IC 443 exhibits extremely strong radiative recombination continua (RRC). In order to study the spectrum quantitatively, we construct a semi-phenomenological model with bremsstrahlung, emission lines, and RRC. We fit the spectrum with this model and obtain reasonable agreement. By using this new model fitting, electron temperatures are obtained in three independent ways: the line flux ratios of Kbeta-Kdelta to Kalpha, the bremsstrahlung shape, and the RRC width. On the other hand, the ionization temperature is obtained by the flux ratio of H-like to He-like Kalpha lines. The fact that ionization temperature (1.1-1.4 keV) is higher than the electron temperature (0.4-1.0 keV) indicates the plasma is in an overionized state, which is very unusual for SNRs., 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: AA0064574048, レポート番号: JAXA-SP-09-008E},
