This electrically driven oil pump comprises: an oil pump having a pump rotor rotatably supported within a pump chamber located between a pump plate and a pump housing; a rotating shaft affixed to the pump rotor; and a motor which has a motor housing, is directly connected to the rotating shaft, and rotationally drives the pump rotor. Further, the motor-side end surface of the pump housing and the pump housing-side end surface of the motor housing are adjacent to each other. Also, the oil pump and the motor are axially fastened to each other by a plurality of fastening bolts at positions radially inside both the outer diameter of the motor housing and the motor-side outer diameter of the pump housing.
