PROBLEM TO BE SOLVED: To provide a resolver that includes a magnetic shield member shielding a rotor and stator from an external magnetic flux and nonetheless is easily attached to an object.SOLUTION: A resolver 100 comprises: a stator 11 that has a stator core 12 around which a three-phase coil 13 is wound; a ring-shaped rotor 21 that is provided on an outer peripheral side of the stator core 12 and is rotatable; a resin molded article 15 that has an electrical insulation property, and is integrally provided in the stator core 12 and supports the stator core 12; and a magnetic shield plate 1 that is provided in the resin molded article 15 so as to be adjacent to the stator 11 and the rotor 21 in a direction of a rotation center axis of the rotor 21, and has permeability. The magnetic shield plate 1 extends over further than the rotor 21 in a radial direction of the rotor 21 from the resin molded article 15, and is insulated from the stator core 12 by the resin molded article 15. |
