  Temperature and abundance distributions of the intra-cluster medium (ICM) in
the NGC 507 group of galaxies were studied with Suzaku. Observed concentric
annular spectra were well-represented by a two temperature model for ICM, and
we found steeper abundance gradients for Mg, Si, S, and Fe compared with O in
the central region. Abundance ratios of alpha-elements to iron were found to be
similar to those in other groups and poor clusters. We calculated metal
mass-to-light ratios for Fe, O and Mg (IMLR, OMLR, MMLR) for NGC 507, and
values for different systems were compared. Hotter and richer systems tend to
show higher values of IMLR, OMLR, and MMLR. OMLR and MMLR were measured to an
outer region for the first time with Suzaku, while IMLR was consistent with
that with ASCA. We also looked into 2-dimensional map of the hardness ratio,
but found no significant deviation from the circular symmetry.
