An inverter is disposed adjacent to one end of a motor in a rotational axis direction. The inverter includes a plurality of power modules, 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. The smoothing capacitor and each of the power modules are disposed in an inner portion of the thin case and arranged on the same plane orthogonal to the rotational axis direction. The busbars are formed to extend in the circumferential direction. An inner edge portion of each of the busbars has an arc shape or a circular shape.
