An insulator is arranged to cover a resolver stator core and includes a cover portion arranged to cover a core back portion and a tooth cover portion for covering a corresponding tooth. In the cover portion, a bridge pin is disposed to project axially upward. After a conductive wire is wound around a tooth, and hooked on the bridge pin, the conductive wire is wound around another tooth. In the case where the insulator is formed by injection molding, an injection gate scar portion is formed on a top surface of the bridge pin, at a position radially outside a crossover portion of the conductive wire, on a top surface of an inner wall of the tooth cover portion, or on a back surface of the insulator.
