 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, We report the spectral and timing analysis of 14 Seyfert galaxies observed with Suzaku, in order to decompose X-ray spectral components. The reflection component via a torus is considered to be less variable, while the varible component is considered to come from the central engine directly. Using this consideration, we tried to decompose a direct component and a reflection component. We compared the spectral parameters obtained by spectral fitting with direct nuclear component plus reflection with those obtained from the difference spectra between high and low state. In particular, we focus attention on the power-law photon index and the Fe-Ka line. As a result, the photon index, the Fe line intensity, and the reflection fraction is almost the same between high and low state. However, some of them are not the case, and the equivalent width of Fe-Ka line against the best-fit reflection component is unreasonable for some objects. These indicate that two-component model is valid for most of Seyfert galaxies, but the behavior of some Seyfert galaxies cannot be explained by two-conmponent model., 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: AA0064574141, レポート番号: JAXA-SP-09-008E},
