摘要:
A method for manufacturing a mold for molding an optical element, wherein the mold comprising a base material having a molding base face and a covering layer provided on the molding base face of the base material, and an upper surface portion of the covering layer located above the molding base face forms a molding face, the method including: a covering step for forming a covering layer on the molding base face of the base material; a pressurizing step for pressurizing a surface of the covering layer; and a high-precision processing step for forming a molding face by applying high-precision processing onto the surface of the covering layer subsequent to the pressurizing step.
