Abstract: No consideration is given to heat transferred from a semiconductor module to a capacitor via a bus bar module. The heat generated by a semiconductor module (1) is transferred to a bus bar module (3) via a DC terminal (1A) of the semiconductor module (1). As illustrated in FIG. 4(B), the heat transferred to the bus bar module 3 is then transferred to the pressing member 5 via the annular conductor 8 and the bolt 5A. Since the pressing member 5 is in close contact with the second cooler 2B, the heat transferred to the pressing member 5 is cooled by the second cooler 2B. On the other hand, the heat transferred to the convex portion 6A of the housing 6 is transferred to the first cooler 2A via the housing 6 and cooled. As a result, in the configuration in which a capacitor (4) is connected to the semiconductor module (1) via the bus bar module (3), the heat transferred from the semiconductor module (1) to the capacitor (4) can be suppressed.
