PROBLEM TO BE SOLVED: To integrally mold a resin molding of a constitution in which a pushbutton is disposed on a molding body. SOLUTION: A previously molded (molding) pushbutton B1 is inserted into a mold M for molding. In this state, a body molding space 26 for molding an upper case (molding body) and a variable thin part molding space for molding variable thin parts are formed in the mold M of upper and lower molds M1, M2 and slide molds S1, S2 for constituting the mold M. In this state, a molten resin as a secondary raw material is injected in a cavity of the pushbutton B1 from a gate 36 of the mold communicating with a gate communicating hole of the pushbutton B1.
