A collector plate (14) is connected to an output terminal (16). The collector. plate (14) is made such that heat capacity per unit area of a neighboring region (14A) thereof, which is near to a portion where the output terminal (16) is connected, is different to the heat capacity per unit area of other regions (14B, 14C). More specifically, the other regions (14B, 14C) are formed such that the heat capacity per unit area thereof is smaller than that of the neighboring region (14A).
(ZH) 集电板(14)连接到输出终端(16)。集电板(14)是做成这样的:其邻近区域(14A)的每单位面积热容与其他区域(14B,14C)的每单位面积热容不同,该邻近区域(14A)靠近输出终端(16)连接的部分。更具体地,其他区域(14B,14C)是这样形成的:其每单位面积热容小于邻近区域(14A)的每单位面积热容。
