ABSTRACT:
A method of manufacturing a resin molding according to the present invention is made by joining first and second resin molded parts. The method includes molding a concave portion when molding the first part, molding a convex portion which has a through-hole in a central portion thereof when molding the second part, mating the concave portion with the convex portion so that a cavity in communication with one end of the through-hole is configured between the concave and convex portions, and holding, with a jig, the first and second parts which the cavity is configured therebetween. Additional steps include connecting a tip of an injection nozzle for injecting a molten resin into the cavity with the other end of the through-hole, and filling the molten resin into the through-hole and the cavity from the injection nozzle so that the concave and convex portions are integrally joined by the resin.
