A resin molding is made by integrally joining a first resin molded part configured with a concave portion and a second resin molded part configured with a convex portion so that the concave portion and the convex portion are mated together. The resin molding includes a cavity that is in communication with the convex portion and the concave portion when the convex and concave portions are mated into each other, and a joining resin filled into the cavity. The first and second molded parts and the joining resin are composed of the same resin or similar resins.
