Abstract:
1. 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, the covering layer comprising a heat insulating layer including ceramics, and an upper surface portion of the covering layer located above the molding base face forms a molding face, the method comprising: a covering step for forming a covering layer on the molding base face of the base material to make a rough processed core; a pressurizing step for pressurizing a surface of the covering layer of the rough processed core, and facilitating a deformation of the heat insulating layer for suppressing the deformation during a continuous molding of the optical element; and a high-precision processing step for applying high-precision processing onto the surface of the covering layer subsequent to the pressurizing step, to precisely shape the molding face.
