PROBLEM TO BE SOLVED: To provide an integrately molded product formed of a skin material and a base of superior design having a ridge section of the skin material of the square and sharp shape and provided with the superior design of not forming creases on the skin material. SOLUTION: As a skin material 2 is stretched gradually in two stages, preliminary press molding and then gas pressure molding, there is no fear that breakage is generated on the ridge section 2a of the skin material 2. Also the ridge section 2a of the skin material 2 can be sucked directly, and the suction force on the ridge section 2a is large. Also the ridge section 2a of the skin material 2 can be pressurized by compressed air from the back side. What is more, the skin material 2 is not heated up to the softening temperature before the skin material is vacuum sucked, and there is no fear of generating creases on the skin material 2.
