Zusammenfassung:PROBLEM TO BE SOLVED: To provide an electric pump capable of attaining at least one of enhancement of heat radiation efficiency, reduction of a deviation of heat radiation, improvement of slidability between a cam ring and a vane, and reduction of noise generated from a pump section.SOLUTION: An electric pump 10 comprises: a motor section 30 including a rotary shaft 23; a rotor 32 including a vane groove 322 storing a vane 33; and a pump section 30 including a pump plate 31 including an outer wall section 311 and a cam ring 313 with a cam surface 313a on which the vane 33 slides. The pump plate 31 includes a bottom lid section 318 which is provided integrally with the outer wall section 311 and the cam ring 313. A connection section 319 is provided between the outer wall section 311 and the cam ring 313, and the connection section 319 projects in a direction separating from the bottom lid section 318 and is further provided integrally with the outer wall section 311, the cam ring 313 and the bottom lid section 318.
