A decorative transfer material includes a base film, a decorative metal vapor deposition layer, a metallic reinforcing layer covering the whole rear face of the metal vapor deposition layer to thereby reinforce the metal vapor deposition layer, a retainer layer for securing the metallic reinforcing layer to the base film, and an adhesive layer for bonding the metallic reinforcing layer to a to-be-decorated object molded by resin. The metallic reinforcing layer is formed of a metallic powder resin layer or a metallic foil layer. After the transfer material is set in dies for injection molding, the dies are closed. Simultaneously with formation of synthetic resin injected into the in-mold dies, the resin is bonded with the metallic reinforcing layer of the transfer material by the adhesive layer. Thereafter, the in-mold dies are opened and the base film of the transfer material is removed, whereby a decorated article is obtained.
