Claim 5:
6. A method for manufacturing a connector by insert molding by arranging a core resin portion having a plurality of connector terminals arranged therein and one or more through nuts facing the core resin portion and each including a penetrating screw hole in a mold and injecting a resin material for an outer resin portion for covering the core resin portion and the through nut into the mold, comprising:
causing a nut facing surface of the core resin portion and an inner end surface of the through nut to face each other in the mold and causing the mold and an outer end surface of the through nut to face each other; and
causing a gate of the mold for the resin material to face an opposite side surface of the core resin portion located on a side opposite to the nut facing surface facing the inner end surface of the through nut and closing an opening of the screw hole located in the inner end surface by the nut facing surface of the core resin portion receiving a pressure during injection of the resin material when the resin material is injected toward the opposite side surface from the gate,
wherein a plating layer is formed on an entire surface of the through nut defining the screw hole.
