Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a molding die for an optical element which allows excellent cutting property and improved dimensional accuracy while maintaining low cost and easy handling. SOLUTION: An amorphous alloy MG having a supercooled liquid zone is attached on a base body 10 which is made of a tough steel or the like. An optical surface transcript plane MGa to shape an optical surface and/or a dimensional reference surface transcript plane MGb to shape a dimensional reference surface on the optical element are formed on the alloy MG. When cutting and shaping the plane MGa or MGb, cutting property is secured as the cutting is performed on the alloy MG. When hot press molding is performed to form the plane MGa or MGb, molding property is excellent, lower capacity is acceptable for heater H and faster heating is feasible as the press formed portion is amorphous alloy MG.
