Abstract: A vehicle interior board which has less deterioration and peeling near an end portion of a metal plate, has high quality, is thin, lightweight, and has high strength and excellent productivity. The vehicle interior board includes a pair of metal plates and a foamed polyurethane layer formed between the pair of metal plates. At the peripheral edge portion of the vehicle interior board, the foamed polyurethane layer covers peripheral end portions of the metal plates and is formed flush with outer surfaces of the metal plates. This makes it possible to suppress oxidation of the peripheral end portions which are cutting surfaces of the metal plates. Further, bonding is good between the metal plates and the foamed polyurethane layer. Further, it is possible to prevent peeling of the metal plates, chipping of the foamed polyurethane layer, and the like. Furthermore, it is easy to demold a vehicle interior board.

Abstract: Included are a first board having a hard polyurethane foam layer formed in a space sandwiched between a pair of thin plates, and a second board having a porous structure where a recessed groove is formed in one main surface, a part of the second board being arranged in the space and joined to the first board. The hard polyurethane foam layer is also formed in gaps between the thin plates and the second board to join the boards. Thus, the step of molding the first board can join and integrate the boards, and mold a bendable, lightweight, and very strong vehicle interior board. Therefore, the vehicle interior board can be reduced in number of parts, simplified in manufacturing process, and improved in productivity.
