<P>PROBLEM TO BE SOLVED: To provide an electric pump for improving assembly workability, supplying stable products, and surely preventing leak of cooling water. Ž<P>SOLUTION: The electric pump 1 includes a bulkhead part 7 in a housing 2. An inside of the housing 2 is separated by the bulkhead part 7 to form a motor chamber M at an inside and a pump chamber P at an outside. A stator 11 is disposed in the motor chamber M, and a rotor 25 supported rotatably to the stator 11 and an impeller part 30 rotating together with the rotor 25 as one unit are disposed in the pump chamber P. The housing 2 is composed of a housing body 4 forming the motor chamber M provided with the bulkhead part 7 and a cover 5 provided at a front side of the bulkhead part 7. The housing body 4 and the cover 5 are composed in such a manner that the same is divided in a rotary shaft direction of the rotor 25, and a spigot part 78 enabling spigot fitting of the housing body 4 and the cover 5 is formed.
