  We studied the temperature and abundance distributions of intra-cluster
medium (ICM) in the Abell 262 cluster of galaxies observed with Suzaku. Abell
262 is a bright, nearby poor cluster with ICM temperature of ~2 keV, thus
providing useful information about the connection of ICM properties between
groups and clusters of galaxies. The observed spectrum of the central region
was well-represented by two temperature models, and the spectra for the outer
regions were described by single temperature model. With the XIS instrument, we
directly measured not only Si, S, and Fe lines but also O and Mg lines and
obtained those abundances to an outer region of ~0.43 r_180 for the first time.
We found steep gradients for Mg, Si, S, and Fe abundances, while O showed
almost flat abundance distribution. Abundance ratios of alpha-elements to Fe
were found to be similar to those of the other clusters and groups. We
calculated the number ratio of type II to type Ia supernovae for the ICM
enrichment to be 3.0 +- 0.6 within 0.1 r_180, and the value was consistent with
those for other clusters and groups. We also calculated metal mass-to-light
ratios (MLRs) for Fe, O and Mg (IMLR, OMLR, MMLR) with B-band and K-band
luminosities of the member galaxies of Abell 262. The derived MLRs were
comparable to those for other clusters with kT = 3-4 keV.
