PROBLEM TO BE SOLVED: To provide a mold for molding an optical surface capable of easily forming fine projections (or cavities) to the optical surface of an optical element on the basis of an idea quite different from a conventional one, the optical element having the optical surface and a master mold for forming a lens and the mold for molding the optical surface. SOLUTION: Since the cavities corresponding to a plurality of projections C are formed to the optical surface of the lens molded by optical molding surfaces 10a and 11a, which are formed by molding an amorphous alloy MG having a supercooling liquid region so as to mold the optical surface of the lens, so as to form a plurality of the projections C to the optical surface of the lens by transfer, even if the projections C must be formed at an interval of several ten - several hundred nanometer, they can be easily formed by transfer without requiring machining. |
