In a drive unit, a motor and an inverter having power modules are disposed adjacent in an axial direction of the motor. In the motor, first and second coil groups, each including one U-phase coil, one V-phase coil, and one W-phase coil, are provided. The power modules constitute first and second power module groups that are connected in parallel. The first and second power module groups each include one U-phase power module, one V-phase power module, and one W-phase power module. A distance between the U-phase power module of the first power module group and the U-phase coil of the first coil group, a distance between the V-phase power module of the first power module group and the V-phase coil of the first coil group, and a distance between the W-phase power module of the first power module group and the W-phase coil of the first coil group are equal.
