PROBLEM TO BE SOLVED: To provide a resin molded body which exhibits metallic texture and glittering appearance leading to high-quality texture, by molding a ferromagnetic glittering agent added to the viscous body of a molten resin by performing three-axis orientation control in which the orientation of the ferromagnetic glittering agent is adjusted by applying a required rotating magnetic field, and orientation distribution control in which the ferromagnetic glittering agent is shifted so as to be concentrically distributed.SOLUTION: A resin molded body 12 includes a polymeric material, such as a thermoplastic resin, a thermosetting resin, elastomer or rubber, to which a predetermined amount of a ferromagnetic glittering agent 10 having shape anisotropy is added. At a time when the polymeric material is in a molten resin state inside of a mold cavity, the polymeric material is subjected to three-axis orientation control and orientation distribution control performed by applying a rotating magnetic field to the molten resin at a required position, adjusting the orientation of the ferromagnetic glittering agent mixed in the molten resin, and shifting the ferromagnetic glittering agent mixed in the molten resin in a required direction, and the ferromagnetic glittering agent 10 mixed in the molten resin is then shifted to a design surface side to be thereby concentratedly distributed for orientation and molded. |
