PURPOSE:To manufacture efficiently a high-quality molded article, by a method wherein a transfer foil to be constituted by providing a protuberant printed layer, a peel ply, an opacifying ply and an adhesive bond on a holding material in this order is held on a wall surface of the inside of a mold and thermoplastic resin is injected from an adhesive bond side of the transfer foil. CONSTITUTION:A transfer foil 8 constituted by providing a protuberant printed layer 2, a peel ply 4, an opacifying ply 6 and an adhesive bond 7 on a holding material 1 in this order is held on a smooth wall surface of the inside of a mold so that the back of the holding material is confronted with a core wall surface, and a molded article 14 to the surface of which the peel ply 4, the opacifying ply 6 and the adhesive bond 7 are transferred through heat and pressure at the time of molding is obtained by injecting heated and softened thermoplastic resin 11 from a side of the adhesive bond of the transfer foil. As the transference is performed simultaneously with injection molding by holding the transfer foil having the protuberant printed layer 2 within an injection molding die like this, an uneven molded article superior in performance can be produced efficiently without having a matter that a hollow part is inferior in adhesion properties to the molded article.
