Abstract:
An electric pump according to an aspect of the present invention is provided with a motor, a pump, an electric pump case, a pressure sensor apparatus that measures the pressure of a fluid pressurized by the pump, and a circuit board. The pump has: a pump gear that rotates in association with the rotation of a shaft; a pump chamber that houses a recessed pump gear from the surface of one side in the axial direction to the other side in the axial direction; and a pump body that has a through-hole that has openings at both ends in the axial direction so as to have the shaft inserted therethrough, the opening at the one side in the axial direction being open to the pump chamber. The pressure sensor apparatus has: a pressure sensor apparatus body that is arranged between the pump and the motor in the axial direction; and an electric connection cable that electrically connects the pressure sensor apparatus body and the circuit board. The electric connection cable is drawn around passing through the radially inner side of the electric pump case, from the pressure sensor apparatus body to the circuit board.
