Inverter circuits formed of a plurality of power semiconductor devices are stored in a casing of a power module. An output terminal provided at one end side of the casing is connected to one inverter circuit. An output terminal provided at the other end side of the casing is connected to another inverter circuit. An output terminal configured to allow electric connection with an output terminal located at the opposite side by a busbar is further provided at each one end side and the other end side. By disposing the busbar appropriately, output from both inverter circuits can be provided from any of the one end side and the other end side. An output terminal configuration can be realized that allows improvement in the degree of freedom for arrangement and versatility in circuit designing with respect to the position relationship with the electric load.
