PROBLEM TO BE SOLVED: To provide a power module including a three-phase inverter for two systems, the power module being able to reduce inductance in an internal wire.SOLUTION: A power module 3 comprises: a multi-layer circuit substrate 30; and a first three-phase inverter 6 and a second three-phase inverter 7, mounted on the multi-layer circuit substrate 30 so as to be arranged in layers. The positive-electrode-side power source wire 71 of the first three-phase inverter 6 and the negative-electrode-side power source wire 102 of the second three-phase inverter 7 are arranged such that at least respective parts face in a layering direction of the multi-layer circuit substrate 30 and currents flow in both the wires in opposite directions in the facing section. The negative-electrode-side power source wire 72 of the first three-phase inverter 6 and the positive-electrode-side power source wire 101 of the second three-phase inverter 7 are arranged such that at least respective parts face in the layering direction of the multi-layer circuit substrate 30 and currents flow in both the wires in opposite directions in the facing section.SELECTED DRAWING: Figure 6 【課題】２系統分の三相インバータを含むパワーモジュールであって、内部配線のインダクタンスを低減できるパワーモジュールを提供する。【解決手段】パワーモジュール３は、多層回路基板３０と、互いに積層配置されるように多層回路基板３０に実装された第１の三相インバータ６および第２の三相インバータ７とを含む。第１の三相インバータ６の正極側電源配線７１と第２の三相インバータ７の負極側電源配線１０２とは、少なくとも一部が多層回路基板３０の積層方向に対向しかつその対向区間において当該両配線に互いに反対方向に電流が流れるように配置されている。第１の三相インバータ６の負極側電源配線７２と第２の三相インバータ７の正極側電源配線１０１とは、少なくとも一部が多層回路基板３０の積層方向に対向しかつその対向区間において当該両配線に互いに反対方向に電流が流れるように配置されている。【選択図】図６
