PROBLEM TO BE SOLVED: To enable recycling of trim parts for a car obtained by integrating a board core material, a pad material and a skin material using high frequency welder processing. SOLUTION: A high frequency weldable polyolefinic resin foam is used as a pad material 30 and a high frequency weldable polyolefinic resin sheet is used as a skin material 40 and high frequency welder processing is applied to a board core material 20, the pad material 30 and the skin material 40 to inexpensively manufacture trim parts 10,100. Further, a polyolefinic resin is used in both of the pad material 30 and the skin material 40 to collectively and simply perform recycling.
