ABSTRACT:
A door panel that is light in weight and has sufficient strength is provided. A door panel has an outer panel, an inner panel, and a foamed material filling a space between the outer panel and the inner panel. The inner panel is formed by means of press molding so as to have an uneven surface with adhering portions and a raised portion. The adhering portions are affixed to the inner surface of the outer panel, and the space is formed between the raised portion and the outer panel. The outer panel has a thickness ranging from 1.2 to 5.0 times that of the inner panel. A hemmed portion is formed by folding the peripheral edge of the outer panel so as to curl over the peripheral edge of the inner panel and then pressing down the folded part.
