PROBLEM TO BE SOLVED: To provide an electric pump having no electric problem between an output shaft of a motor and hot water in a pump case. SOLUTION: A driving magnet 23 is covered by an insulating cap 28 provided on a motor support part 26 while regulating the position. Thereby, a double insulating structure is achieved between the output shaft 22 of the motor 21 and the hot water in the pump case 25 with the usage of the cap 28, and therefore, the electric pump having no electric problem can be achieved.
