<P>PROBLEM TO BE SOLVED: To take proper measures against heat transmitted from a switching element to an external circuit element through a bus bar. <P>SOLUTION: The bus bars 14P, 14N have a high-voltage bus bar 14P and a low-voltage bus bar 14N, respectively. At least either one of the high-voltage bus bar 14P and the low-voltage bus bar 14N includes reciprocating structure sections 34P, 34N reciprocating through an outside portion and an inside portion. The outside portion and the inside portion of the reciprocating structure sections 34P, 34N face each other at a predetermined interval. <P>COPYRIGHT: (C)2013,JPO&INPIT |
