Abstract: A vehicle interior board which is thin, lightweight, has high strength, has less degradation, peeling and the like near an end portion of a metal plate, and has high quality and excellent productivity; and a method for manufacturing the same. The vehicle interior board includes a pair of metal plates and a foamed polyurethane layer formed between the pair of metal plates. A projecting ridge projecting outwardly and extending in a predetermined direction along the outer surface is formed on an outer surface of the metal plate. Thus, it is possible to obtain desired strength and rigidity even when the metal plates or the foamed polyurethane layer are thinned or when a lightweight aluminum plate or the like is adopted as the metal plates. Therefore, it is possible to reduce weight of a vehicle interior board.
