抄録（英）
We present results from a Suzaku observation of the Seyfert 1.9 galaxy NGC 7314. The light curve in the 2-10 keV band shows rapid variability on timescales of approximately 1000 sec. The time-averaged spectrum in 0.5 - 25 keV is explained a model consisting of absorbed and unabsorbed power laws, a reflection continuum and a gaussian at 6.4 keV. The line at 6.4 keV is relatively narrow (sigma approximately 50 eV) and does not vary on a timescale of approximately 10 years. This narrow line is likely to be primarily from distant matter. We analyze spectra in the time intervals with fluxes higher/lower than the mean. The normalization of the absorbed power law varies by a factor 1.6, while the photon index, the amount of the reflection, and the intensity of the Fe line remains constant.
