PROBLEM TO BE SOLVED: To provide an electric motor in which breakage of a stator core can be suppressed at the time of injection molding.SOLUTION: An electric motor includes an annular stator whose outline is molded with mold resin and rotors oppositely arranged on magnetic pole surfaces MF of the stator and rotating. The stator includes a stator core 7 formed with compression-molding of magnetic powder. The stator core 7 includes a rod-like winding body part 7A around which a wire is wound, and a flange 7B protruding from an end of the winding body part in a vertical direction. The magnetic pole surfaces MF facing the rotors are formed on the end of the winding body part 7A and the flange 7B, and out of the magnetic pole surfaces MF, the magnetic pole surface on the winding body part side is formed so as to be closer to the rotor than the magnetic pole surface on the flange side. |
