PROBLEM TO BE SOLVED: To prevent molding failure by discharging air in the cavity of a mold to the outside at the time of molding of a skin-integrated molded product to prevent air from remaining in the skin-integrated molded product. SOLUTION: In an instrument panel 1 equipped with a general cross-sectional part 21 wherein the interval between a skin material 3 and a core material 5 is relatively narrow and the thick-walled cross-sectional part 23 separated from the injection hole of the core material 5 to extend toward a left-hand terminal part and wider than the general cross-sectional part 21 in the interval between the skin material 3 and the core material 5, a weir part 31 is provided to the thick-walled cross-sectional part 23 and the flow of a resin raw material is adjusted so that the flow of the resin raw material passing through the general cross-sectional part 21 and the flow of the resin raw material passing through the thick-walled cross-sectional part 23 meet with each other at the terminal part at the time of injection of the resin raw material.
