The rotary electric machine also includes a rotor with a plurality of magnets that face the teeth, the magnets and teeth separated from each other by a space therebetween. Each of the teeth comprises a head portion facing opposite the magnets, a coil wind-up portion around which the coil is wound up, and an insert portion that can be inserted into the stator yoke core, the insert portion including a groove formed in a portion of the insert portion that protrudes from the stator yoke core, where the groove is fillable with the molding resin to inhibit the teeth from disengaging from the stator yoke core.
