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.
