ABSTRACT:
A metal design panel is constituted by a surface decorative member and a thermoplastic resin member, which are firmly and integrally combined together. A plurality of through holes or dimples are formed at prescribed positions of a metal plate panel, which serves as a surface decorative member, in conformity with an outline of a product completed in manufacture. The metal plate panel is subjected to trimming to remove an unwanted peripheral portion, thus extracting a metal plate therefrom. The metal plate is arranged in a metal mold, into which a melted thermoplastic resin is injected to form a resin layer, which is firmly combined with the metal plate. Alternatively, a core member is formed and extracted from the metal plate panel and is combined with a resin layer upon injection molding.
