PROBLEM TO BE SOLVED: To provide a manufacturing method for a car interior panel with an air bag storage section cover of superior heat fusion bonding properties with a decorative skin for the swelling of an air bag and the destruction, scattering and the like of an air bag storage section cover at the time of spreading, uniformizing the wall thickness of a preset opening and tearing line and molding securely reinforcing ribs. SOLUTION: In a manufacturing method for an interior panel, a thermoplastic elastomer material in the molten state composed of original thermoplastic elastomer and/or styrene thermoplastic elastomer as a main component, which is not cut into two in the notched Izod impact test under the conditions of 10 g/10 minutes melt flow rate or more and 50-1000 MPa bending modulus of elasticity at -30 deg.C, is introduced into a cavity of a compression molding die. Then the compression molding is carried out to manufacture the air bag storage section cover integrated with the interior panel. |
