PROBLEM TO BE SOLVED: To inhibit wear of a rotary shaft end part on a motor part side and reduce rotary resistance. SOLUTION: In this electric pump, a first rotary shaft part 71 extending to an axial one side is used as a rotary shaft of a pump part 3, and a second rotary shaft part 72 extending in an axial another side is used as a drive shaft of the motor part in relation to the rotary shaft 7 supported in through holes 5 provided on partition walls 2 in a housing 1 via a slide bearing 6. A support part 19 receiving the rotary shaft end part 72a in an axial direction and supporting the same is provided on a fixed member 16 opposing to the end part 72a (rotary shaft end part) of the second rotary part 72, a projection part such as a spherical member 20 keeping point contact with another surface is provided on either one of the end surface of the rotary shaft end part 72a and a receive surface of the support part 19, and the rotary shaft end part 72a is supported by the support part 19 at a point contact section.
