An electric pump includes a motor unit rotationally driving a drive shaft, and a pump unit. The pump unit includes a pump rotor that sends the fluid by a driving force of the driving shaft, and a pump housing that covers at least one side of the pump rotor. The pump housing includes an attachment surface extending in the axial direction and in contact with an attached body, first and second flow paths respectively on the suction side and the discharge side, and a partition wall positioned between pump-side openings of the first flow path and the second flow path facing the pump rotor, and extends in a direction along the attachment surface, and locations of attachment-side openings of the first flow path and the second flow path on the attachment surface are displaced from each other on the attachment surface in the axial direction.
