PROBLEM TO BE SOLVED: To provide a method of manufacturing an automotive interior panel which is not influenced by a time factor after a treatment to activate the surface of a polyolefin-based resin core material and demonstrates the successful adhesive properties between the polyolefin-based resin core material and a polyurethane resin skin, even under normal and cold temperature. SOLUTION: The polyolefin-based resin core material after the treatment to activate the surface is used by warming to 60 to 100°C which are higher than a molding tool temperature.
