Abstract: In a related-art resolver, a front and a back of a stator core cannot be distinguished, and it is difficult to mass-produce the resolver while matching directions of shear drops and burrs. Thus, assembly accuracy of the resolver is degraded. Further, productivity and assembling ability are degraded because electromagnetic steel sheets are laminated by rotary lamination. The present invention provides a resolver including: a resolver stator including: a stator core formed of electromagnetic steel sheets, which have teeth, and are laminated without rotary lamination; a one-phase excitation winding; and two-phase output windings; and a resolver rotor arranged to be opposed to the resolver stator, in which the stator core has marks which enable distinction of a rolling direction of the stator core and distinction of a front and a back of the stator core.
