MOLDING DIE, AND MOLDING DIE MANUFACTURING METHOD

摘要

Disclosed is a molding die having a molding face, to which a finely irregular surface structure based on a mother mold is transferred, so that the molding die is durable and can retain the flatness of the molding face.  Also disclosed is a method for manufacturing molding dies (10 and 12) having the finely irregular surface on a molding face (10a).  The method comprises: a mother mold forming step of applying a finely-ridged resist structure (11) based on a resist to an energization part (12a) by using an energization substrate (12) having the energization part (12a) on at least one surface thereof, to thereby form a mother mold (10A); a metal structure forming step of depositing a metal having a thickness corresponding to the height of the resist structure (11), on the energization part (12a), to thereby form a metal structure (13); an energization film forming step of forming an energization film (14) on the surface of the resist structure (11); a reinforcing layer forming step of forming a reinforcing layer (15) on the energization film (14) by a plating treatment; and a mother mold removing step of removing the mother mold (10A) to thereby form the mold having the finely irregular patterns based on the metal structure (13).
