抄録（英）
Suzaku enable us to investigate not only type Ia supernovae products (Si, S, and Fe) but also type II products (O and Mg) in the intra-cluster medium (ICM) to approximately 0.3 r(sub180) region of clusters and groups of galaxies. We measured the metal abundances of the ICM of the clusters and groups between approximately 1 and approximately 4 keV and also calculated the Fe, O and Mg mass-to-light ratios (IMLR, OMLR, MMLR) with both B-band and K-band luminosities. The OMLR and MMLR were measured to 0.3 r(sub180) region in the ICM for the first time with Suzaku, while the resultant IMLR were consistent with those with ASCA. The MLRs of many groups seem to be lower than those of clusters. In addition, the values with K-band seem to be smooth for each cluster compared with those with B-band. Observed spatial metal distribution hint that type II products seem to have wider distribution than type Ia products. These suggest that metal enrichment process in the ICM seem to be similar for different clusters, while the MLRs of groups seem to have some scatter.
