The P bus bar 130 includes a connection portion 131, a common wiring portion 132, and a parallel wiring portion 133. The connection portion 131 is a portion connected to the positive electrode terminal of the capacitor C1. In the present example, in the projection view of the P bus bar 130 in the Z direction, the entire portion overlapping with the capacitor C1 is the connection portion 131. Although not shown, the connection portion 131 may be arranged at the portion overlapping with the capacitor C1 in the projection view in the X direction or the Y direction, that is, on the lateral surface of the capacitor C1. The common wiring portion 132 extends from one end of the connection portion 131 in the Y direction. The common wiring portion 132 is a portion of the P bus bar 130 that functions as the above-described common wiring 11P. As a result, the one upper and lower arm circuit 10 included in the power module 110 and the capacitor C1 are not individually connected to the above-described VH line 12H, but are commonly connected to the above-described VH line 12H. The common wiring portion 132 has a shorter length in the X direction, that is, a shorter width than the connection portion 131. The common wiring portion 132 connects to a central portion of the connection portion 131 in the X direction. The common wiring portion 132 is substantially flush with the connection portion 131 and extends in the Y direction. A part of the common wiring portion 132 projects to the outside of the protective member 180.
