Provided is a metal molding die for providing micro components at a low cost in a short time by using an optical molded structure formed by an optical molding method. In a method for manufacturing a molding die, a three dimensional structure is formed by applying a light curing liquid resin composition, irradiating the light curing liquid resin composition with light and removing uncured portion of the light curing liquid resin composition, and a molding die is formed based on the three dimensional molded structure. A metal film for covering the three dimensional molded structure is formed, the three dimensional structure covered with the metal film is removed, and the metal film is permitted to be the molding die. |
