The parallel wiring portion 133 has substantially an L shape. The parallel wiring portion 133 has a parallel portion 134 extending in the Y direction from a boundary portion with the connection portion 131 and a bent portion 135 that is bent with respect to the parallel portion 134 and extend in the Z direction. Therefore, the parallel portion 134 is also referred to as a Y direction extension portion. The bent portion 135 is also referred to as a Z direction extension portion. The parallel portion 134 extends in the Y direction towards the opposite side to the common wiring portion 132. The parallel portion 134 is substantially flush with the connection portion 131 and extends in the Y direction.
In the projection view in the Z direction, the parallel portion 134 overlaps with at least a part of each of the seven main terminals 70C and 70E of the semiconductor device 20U. The parallel portion 134 extends up to substantially the same position as the projection tip end portions of the main terminals 70C of the semiconductor device 20U, and overlaps with the entire projected portions of the three main terminals 70C in the projection view. The four main terminals 70E extend up to a position that is farther from the capacitor C1 than the parallel portion 134.
