The parallel wiring portion 143 at least functions as a wiring electrically connecting the negative electrode terminal of the capacitor C1 and the lower arm 10L of the upper and lower arm circuit 10, that is, a wiring connecting the upper and lower arm circuit 10 and the capacitor C1 in parallel. Further, in the present example, the parallel wiring portion 143 also functions as a wiring electrically connecting the lower arm 10L to the common wiring 11N, that is, to the common wiring portion 142. The parallel wiring portion 143 extends from an end of the connection portion 141, the end being opposite to the common wiring portion 142.
A width of the parallel wiring portion 143 is narrower than that of the connection portion 141. The parallel wiring portion 143 is extended with a constant width. The parallel wiring portion 143 is arranged on the side opposite to the parallel wiring portion 133 with respect to the center line CL1 so as not to extend over the center line CL1 of the capacitor C1. The parallel wiring portion 143 connects to the connection portion 141 on the side adjacent to the semiconductor device 20L (semiconductor chip 40L) in the alignment direction of the semiconductor devices 20U and 20L.
