Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a resin molding die capable of stably forming a molding surface of a fine resin layer and readily releasing the molded product with small force in manufacturing a resin junction optical element by providing a resin layer having a predetermined shape molded on the optical element substrate, and to provide a method for manufacturing the resin junction optical element used therewith. SOLUTION: In a resin molding die for manufacturing a resin junction optical element by providing a resin layer having a predetermined shape molded on a optical element substrate, a groove 14 is provided in at least one portion, the groove being present from a die surface region 12 positioned outside of an optical effective diameter portion of the resin layer for molding the optical effective peripheral portion to a mold surface resin positioned outside of the edge portion of the resin layer without molding the resin layer.
