PROBLEM TO BE SOLVED: To improve the adhesion between a stator core and an insulator, in a stator having the stator core with teeth and the insulator to be mounted on the teeth. SOLUTION: The stator core 100 includes its cylindrical body 110, and a tooth 120, protruding from the inner peripheral surface of the main body 110 to the side of a central axis in the body 110. The insulator 200 has a basement 210 formed as a substantially rectangular cylinder so as to house the tooth 120 therein, and a flange 220, protruding externally from the end of the basement 210 at the side remote from the central axis of the body 110. A pair of grooves 130 are formed, extending substantially in parallel in the axial direction of the body 110 at the base of the tooth 120. A pair of protrusions 240 are formed so as to protrude to the inner side of the basement 210 fit into the groove 130, at the end of the basement 210 separating from the central axis of the body 110.
