To easily and directly connect an output terminal of a power module with a coil of a rotary electric machine while preventing reduction in the productivity of the power module.SOLUTION: A semiconductor device for power for supplying power to a rotary electric machine comprises a plurality of power modules which are respectively connected to a plurality of coils of the rotary electric machine. Each of the plurality of power modules includes: a body part; and an output terminal which is directly connected to the corresponding coil of the plurality of coils. The body part comprises: a first edge when viewed from the axial direction along a rotary shaft of the rotary electric machine; a second edge; and an oblique part connected to the first edge and the second edge. The output terminal is provided so as to be on the inner side of a region surrounded by a first virtual straight line along the first edge, a second virtual straight line along the second edge and the oblique part when viewed from the axial direction.SELECTED DRAWING: Figure 2 【課題】パワーモジュールの生産性の低下を防止しつつ、パワーモジュールの出力端子と回転電機のコイルとを容易に直接接合すること。【解決手段】回転電機に電力を供給する電力用半導体装置であって、回転電機の複数のコイルとそれぞれ接続される複数のパワーモジュールを備え、複数のパワーモジュールはそれぞれ、本体部と、複数のコイルのうち対応するコイルと直接接合される出力端子と、を備え、本体部は、回転電機の回転軸に沿った軸方向から見たとき、第１端縁と、第２端縁と、第１端縁及び第２端縁に接続された斜辺部と、を有し、出力端子は、軸方向から見たとき、第１端縁に沿う第１仮想直線と、第２端縁に沿う第２仮想直線と、斜辺部と、で囲われた領域の内側に収まるように設けられる。【選択図】図２
