Abstract: A resin part includes a plate-shaped molded main body that is constituted of an injection-molded product. Of plate surfaces of the molded main body, a surface on an opposite side to a surface requiring surface accuracy constitutes a pressure-application surface to which pressure is applied by a movable insert. A parting line is formed on the pressure-application surface by the movable insert to satisfy the following relationship: (t/4)≤x≤(3t/2), where x is a distance from an end edge part of the molded main body to the parting line and t is a thickness of the molded main body.

Abstract: A resin part includes a molded main body that has a plate shape with a longitudinal direction and is constituted of an injection-molded product. The resin part has a gate portion that is a vestige of a resin injection gate. The gate portion is located in an end face part of the molded main body to cross a position corresponding to a center of gravity of the molded main body; the end face part extends in the longitudinal direction of the molded main body.
