Abstract: An aspect of an electric pump of the present invention is an electric pump attached to a predetermined object. The electric pump includes a motor having a rotor rotatable about a center axis extending in an axial direction, a pump mechanism coupled to the rotor, a circuit board located radially outside the motor and having a plate face directed in a radial direction, an electrolytic capacitor attached to the plate face of the circuit board, and a housing that houses the motor, the pump mechanism, the circuit board, and the electrolytic capacitor therein. The housing has a mounting face attached to a predetermined object. The mounting face is a face directed radially outward. The plate face of the circuit board is disposed along a direction intersecting the mounting face. The electrolytic capacitor is disposed at a position closer to the mounting face than the center axis in the direction orthogonal to the mounting face.

Abstract: An electric pump includes: a motor including a shaft; a pump mechanism coupled to an axial one side of the shaft; a circuit substrate located outward in a radial direction orthogonal to the axial direction of the shaft, and a housing capable of accommodating the motor and the circuit substrate. The circuit substrate includes a plate surface facing the shaft and following the axial direction. The housing includes a motor housing part, a substrate housing part, a pump housing part, and an attachment plate part located outward in a radial direction. The attachment plate part includes an attachment surface facing the shaft and following the axial direction. The motor and the pump mechanism are located on an inner angle side of an angle at which a third surface including the plate surface and a fourth surface including the attachment surface intersect.
