PROBLEM TO BE SOLVED: To efficiently obtain a good resin molded object not generating the positional shift of a metal foil or the covering with a resin, in molding the resin molded object including an in-molded metal. SOLUTION: The metal foil having a columnar crystal structure with a thickness of 10-150μm is used to be punched at the time of molding by the shearing force of a mold or the injection pressure of the resin. The adhesion of the resin and the metal foil is made strong by the fine unevenness formed to the back surface of the metal foil or the adhesive layer formed on the back surface of the metal foil. |
