One aspect of the present invention relates to a drive device comprising: a motor having a rotor rotatable about a central axis and a stator; an inverter disposed on one side of the motor in the axial direction and connected to the motor; a power transmission unit disposed on the other side of the motor in the axial direction; and a housing having a motor accommodation space, an inverter accommodation space, and a gear accommodation space. The power transmission unit has a reduction gear that transmits the power of the motor and a differential gear that outputs, from an output shaft, the power transmitted from the reduction gear. The housing has a plurality of mounting portions that are fixed to a vehicle body. The mounting portions each have a first mounting portion, a second mounting portion, and a third mounting portion. The first mounting portion is disposed on the other side of the motor in the axial direction. The second mounting portion is disposed on the one side of the motor in the axial direction. The gear accommodation space has a differential gear accommodation space that accommodates the differential gear.
