An inverter (300) is disposed toward an opening in a motor side metal housing (201). A power module (301) is disposed on a metal cover (207) that is in contact with the metal housing (201). The power module (301) includes a semiconductor element, a metal terminal connected to the semiconductor element, and resin that seals the semiconductor element and the metal terminal. A metal plate (306) is disposed on a surface of the power module (301) that is positioned opposite the metal cover (207). Heat generated by the power module (301) is dissipated from the metal cover (207) and from the metal plate (306). This improves the heat dissipation performance. Thus, the size of the power module can be reduced.
