An inverter is disposed adjacent to one end of a motor in a rotational axis direction. The inverter includes a plurality of power modules each including a switching element, a smoothing capacitor, busbars that connect the power modules to the smoothing capacitor, and a thin case that accommodates these components. The plurality of power modules are disposed at the periphery of the smoothing capacitor and arranged in the circumferential direction. The busbars are formed to extend in the circumferential direction. An inner edge portion of each of the busbars connected to a terminal of the smoothing capacitor has an arc shape or a circular shape.
