PROBLEM TO BE SOLVED: To provide a manufacturing method for a simultaneously injection-molded and decorated article with a fusion rib, which exposes a molding resin without making a decorating layer transferred onto the fusion rib during decoration concurrent with injection molding. SOLUTION: In this manufacturing method for the simultaneously injection-molded and decorated article with the fusion rib in a lying triangular prism shape, a decorative sheet 4 is arranged in molds (30 and 31); the mold is clamped; the molten molding resin is injected into the molding space part 33 of the mold; the decorative sheet 4, which is positioned in the casting mold part 32 for the fusion rib, is divided; the molding resin is fed into the casting mold 32 for the fusion rib, so as to mold the fusion rib; concurrently with that, a surface layer part of the molding resin is decorated with the decorating layer of the decorative sheet; and the simultaneously injection-molded and decorated article is taken out by opening the mold after cooling.
