Glass molding die

Abstract

To provide a glass molding die which is more excellent in durability than the conventional ones. A glass molding die 10 includes a base body 12, an Au layer 14 which is laminated on a surface of the base body 12, and an Rh layer 16 which is laminated on a surface of the Au layer 14. On a surface of the Rh layer 16, an Ir-containing layer may be further laminated. The Au layer 14 functions as a bonding layer, the Rh layer 16 functions as an anti diffusion layer, and the Ir-containing layer functions as a mold releasing layer. The Au layer 14, the Rh layer 16, and the Ir-containing layer are preferably formed by plating.
