PROBLEM TO BE SOLVED: To reduce deformation caused by a weld line in a multicolor molded article.SOLUTION: In manufacturing a resin molded article including a base part 211 and a packing part 212, the base part 211 is formed so that a cross sectional area in a position where resin materials, which are divided into two and are molten, collide becomes smaller than a cross sectional area in a position where the molten resin materials do not collide, when molding the packing part 212. |
