Abstract
A power module of a drive unit of an electric motor is formed by inserting multiple power transistors, which supply a drive current to a coil wound around a stator or a rotor, and wirings connecting the power transistors in a resin, which is formed in the shape of a plate, by resin molding. Electronic components such as aluminum electrolytic capacitors, a choke coil and a first connector are provided in a board thickness direction of the power module and are electrically connected with the wirings of the power module. Thus, a construction for electrically connecting the wirings of the power module formed by the resin molding and the electronic components can be simplified.
