Summary:PURPOSE: To prevent warping and strain by forming polyethylene layers on both surfaces of a synthetic resin foaming body on both surfaces of which aluminum foils have been bonded, and also by sticking aluminum foils on both the surfaces of the respective polyethylene layers, and then by arranging decorative materials on both the surfaces respectively. CONSTITUTION: A core material panel of a door is formed by making a center of a synthetic resin foaming body 1 and by laminating thereon from both sides aluminum foils 2, polyethylene layers 3, aluminum foils 2, and decorative materials 4 respectively. By the front and rear symmetrical layer construction of different materials like this, strong strength and shape maintenance can be produced, and a core material panel free from warping and strain can be obtained. Further, the waterproofing effect of the polyethylene layers 3 is effectively produced by the joint use of aluminum foils, and even in a region where the temperature difference is large, the core material can prevent warping, dewing, or the like.
