An inverter-control element operates with a power-supply potential supplied to an inverter-control-system power-supply terminal to output a signal for controlling an inverter switching element. A brake control element operates with a power-supply potential supplied to a brake-control-system power-supply terminal to output a signal for controlling a brake switching element. A first metal component includes a plurality of protrusions protruding from a sealing resin, is supported by the sealing resin with a portion embedded in the sealing resin, and is electrically connected to each of the inverter-control-system power-supply terminal and the brake-control-system power-supply terminal.
