A resin molded component includes a flange (20) having a through-hole (30). A concave portion (40, 45) is formed on the surface of the flange (20) that faces the component on which the flange is fitted. Flows of a molten resin material meet each other at a meeting portion in a region around the through-hole (30) during a molding process, and a weld line is formed at the meeting portion. The concave portion (40, 45) is formed upstream of the meeting portion at which the flows of the molten resin material meet each other, and in the vicinity of the through-hole (30). The thickness of the resin material in the bottom portion of the concave portion (40, 45) is greater than the thickness of the resin material in the thinnest portion of the wall of the concave portion (40, 45). |
