Abstract: An electric oil pump includes a motor unit having a shaft centered on a central axis that extends in an axial direction of the shaft and a pump unit which is disposed on a front side of the motor unit, is driven by the motor unit, and discharges oil. The motor unit includes a rotor that is fixed on a rear side of the shaft, a stator that is disposed outside the rotor in a radial direction, a resin housing in which the rotor and the stator are housed, and a connector assembly that is disposed outside the resin housing in the radial direction. The connector assembly is integrally molded with the resin housing. The pump unit includes a pump rotor installed to the shaft that protrudes from the motor unit and a pump housing in which the pump rotor is housed.
