A motor module includes a motor including n-phase windings where n is 3 or more, a first circuit boar, a first inverter mounted on the first circuit board and connected to the windings, a first passive element group mounted on the first circuit board, a first heat sink in thermal contact with the first circuit board, a second circuit board, a second inverter mounted on the second circuit board and connected to the windings, and a second passive element group mounted on the second circuit board. A first passive element having a highest height in the first passive element group and a second passive element having a highest height in the second passive element group are located between the first circuit board and the second circuit board, and do not overlap each other when viewed along a direction of a rotation axis of a rotor of the motor.
