An interior part 1 for an automobile that is disposed on a front side in the automobile is obtained by integrally molding an instrument panel fascia 10 , a duct 13 and a reinforce member 13 by a blow molding method including: extruding a resin composition into a molten parison P; holding the parison P in a metal mold 2 ; and blowing the air into the parison P to obtain a resin molding. Thus, as compared to an arrangement where each of the members is formed separately, the number of members can be reduced. In addition, the arrangement requires only one type of material, metal mold and a molding device, and does not require an assembly step that is required in the arrangement with separately molded members, resulting in reduced cost.
