To provide an electric pump that can be made small in a radial direction.SOLUTION: An electric pump 100 comprises a motor, a pump mechanism, a control substrate, a motor housing 30, and a substrate housing 60. The substrate housing 60 has a lower case and an upper case 70. A coupling part 201 of the motor housing 30 and the lower case includes respective first sealing faces 193, 191 of the motor housing 30 and the lower case, a first groove 183, and a first seal member 185. The coupling part of the lower case and the upper case 70 includes respective second sealing faces 192, 194 of the lower case and the upper case 70, a second groove 184, and a second seal member 186. The first seal member 185 and the second seal member 186 have an annular elastic body with a flat cross sectional shape long in an upward and downward direction under a non-compressed state.SELECTED DRAWING: Figure 4 【課題】径方向の小型化が可能な電動ポンプを提供する。【解決手段】モータと、ポンプ機構と、制御基板と、モータハウジング３０と、基板ハウジング６０と、を備える電動ポンプ１００。基板ハウジング６０は、下側ケースと上側ケース７０とを有する。モータハウジング３０と下側ケースとの連結部２０１は、モータハウジング３０および下側ケースのそれぞれの第１封止面１９３，１９１と、第１溝１８３と、第１シール部材１８５とを含む。下側ケースと上側ケース７０との連結部は、下側ケースおよび上側ケース７０のそれぞれの第２封止面１９２，１９４と、第２溝１８４と、第２シール部材１８６とを含む。第１シール部材１８５および第２シール部材１８６は、非圧縮状態において上下方向に長い扁平な断面形状の環状弾性体を有する。【選択図】図４
