となる。(Function) In this configuration, the base material is set in a heated state on the molding surface of the slush mold, and then the foamable resin powder is slush-molded onto the base material. Therefore, since the foamed skin material is formed directly on the base material, it is possible to reduce the number of skin material pasting steps. In addition, since the skin material is molded using the powder slush method, there is no risk of the skin material peeling off (lifting) or other appearance defects due to residual stress.Furthermore, since the skin material is a foamed skin material, it is soft. A feeling is given. Therefore, according to the present invention, residual stress in the skin material is eliminated by molding using the powder slush method, and by forming the skin material directly on the base material, both are integrated and the skin material is pasted. It becomes possible to manufacture a base material/foamed skin material integrated structure that can reduce the number of steps and provide a soft feel by foaming the skin material.
