Similarly to the three power modules 110, the three smoothing capacitors C2 are also arranged in the circumferential direction. The power module 110 and the smoothing capacitor C2 are arranged one by one in the axial direction α, and both extend in the tangential direction orthogonal to the radial direction β and extend in the axial direction α. In this case, there are three sets of the power module 110 and the smoothing capacitor C2 arranged in the axial direction α. In each set, the power module 110 is located between one end of the housing 703 and the smoothing capacitor C2. That is, in each set, the arrangement order of the power module 110 and the smoothing capacitor C2 in the axial direction α is the same.
The housing 703 has an installation surface 713a on the outer cooling part 713. The installation surface 713a is a part of the outer peripheral surface formed by the outer cooling part 713, and extends in the tangential direction orthogonal to the radial direction β and the axial direction α. Three installation surfaces 713a are arranged in the circumferential direction γ, and one set of the power module 110 and the smoothing capacitor C2 is installed on one installation surface 713a.
