PROBLEM TO BE SOLVED: To provide a motor which can be miniaturized and can perform resin molding without requiring a post-treatment process. SOLUTION: A frame 2 is made of aluminum, the yoke 5a and tooth 5b of a stator core 5 are projected in the axial direction to cover the upper and lower portions at the coil end 7a of a stator coil 7 and extended to the axial end position of a bobbin to form a yoke projection and a tooth tip projection. The yoke projection is brought into tight contact with the inner surface of the frame, clearance between the yoke projection and the tooth tip projection is resin molded to cover the stator coil, and a permanent magnet is extended to oppose the tooth tip projection in the radial direction.
