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 member is formed from a resin material containing filler and an insulating base polymer as a main component. The resin member includes an alignment layer close to a surface of the resin member. The alignment layer includes the filler aligned in the surface direction and the base polymer filling the space between pieces of the filler. The alignment layer includes a carbonized portion that is carbonized matter of the base polymer, contains graphite, and provides electrical conductivity and thermal conductivity.

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.
