METHOD FOR MANUFACTURING MOLD FOR MOLDING OPTICAL ELEMENT

摘要

This invention provides a method for manufacturing a mold for molding an optical element, which can prevent a change in shape during continuous molding of an insulating layer and can realize high-accuracy transferability. The method for manufacturing a mold (10) for molding an optical element manufactures a mold for molding an optical element, comprising a base material (11) having a molding base face, and covering layers (12) to (15) provided on the base material on its molding base face. Among the surfaces of the covering layers (12) to (15), the upper part of the molding base face of the base material is a molding face. The method comprises a covering step of forming a covering layer on the base material on its molding base face, a pressurizing step of pressing the surface of the covering layer, and a high-precision processing step of subjecting the surface of the coating layers to high-precision processing after the pressing step to form a mold face.
