PROBLEM TO BE SOLVED: To provide an electric pump capable of improving the efficiency of the pump. SOLUTION: In this electric pump 1 of whole peripheral flow type provided with a pump housing 10 provided with a communicating passage for communicating a suction port 12a with a discharge port 32a, a rotor 50 having an impeller 52, and a stator 60 arranged on an outer side in the radial direction of the rotor 50 and constituted by forming an annular flow passage A between a motor case (an in-line part 24, a cover housing 41) storing the stator 60 and the pump housing 10, the motor case is supported in the communicating passage by guide plates 28, 29 for connecting a peripheral wall 25 with an inner peripheral wall 22a of a motor in the radial direction, the impeller 52 is arranged on a suction port 12a side of the flow passage A, and the guide plates include the guide plate 28 forming a section on the downstream side along the axial direction and forming a section on the upstream side by inclining toward an R rear side in the direction of rotation of the impeller 52 and the guide plate 29 forming a through hole 29g for leading a wire 71 for feeding electricity onto a stator 60 side.
