The cluster of galaxies MS 1512.4+3647 ( z = 0.372 ) was observed with Suzaku for 270 ks .
Besides the Fe abundance , the abundances of Mg , Si , S , and Ni are separately determined for the first time in a medium redshift cluster ( z > 0.3 ) .
The derived abundance pattern of MS 1512.4+3647 is consistent with those of nearby clusters , suggesting that the system has similar contributions from supernovae ( SNe ) Ia and SNe II to nearby clusters .
The number ratio of SNe II to SNe Ia is \sim 3 .
The estimated total numbers of both SNe II and SNe Ia against gas mass indicate similar correlation with those for the nearby clusters .
The abundance results of MS 1512.4+3647 is consistent with the standard scenario that the SN II rate history roughly follows the star-formation history which has a peak at 1 < z < 2 and then declines by about one order of magnitude toward z \sim 0 .
The similar number of SNe Ia to the nearby clusters suggests that the SN Ia rate declines steeply from z = 0.37 to z = 0 and/or SN Ia explosions occurred predominantly at larger redshifts .
