PROBLEM TO BE SOLVED: To provide an electric pump compact in its entire shape, wherein the wall thickness of a casing is made thin so as to increase the magnetic attraction of a rotor magnet and a core with a coil wound around it, and a shaft is supported so as to streamline the flow of a fluid. SOLUTION: The electric pump uses an inner rotor type brushless DC motor, with a housing composed of a pump case 2 and the casing 3, and with a stator assembly 14 having a sensor sealedly formed in resin between the side wall part 8 of the casing 3 and a can 21. A first elastic sealing material 47 is watertightly disposed in a compressed state between the can 21 and the casing 3. The can 21 and a second elastic sealing material 48 are watertightly disposed between the pump case 2 and the casing 3. The pump case 2 and the casing 3 are thus made to be stuck together.
