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.
