PROBLEM TO BE SOLVED: To precisely form the reversal shape of a character, a mark or a pattern, which must be transferred and formed to the surface of a molded product, to the inner surface of a molded cavity without relying on an electroforming method having many points at issue. SOLUTION: The reversal shape of the character, mark or pattern to be transferred and formed to the surface of the molded product is directly carved in the inner surface (2) of the mold cavity (1) for molding a resin by a laser beam (5).
