PROBLEM TO BE SOLVED: To obtain a complex type optical element having a desired shape which improves productivity in replica molding, reduces costs, and satisfies sufficient optical functions. SOLUTION: In a method for producing a complex type optical element, a photo-curable resin is dropped on the surface of a mold having an optically and structurally desirable shape, pressed/packed by a plane or curved surface lens blank, and irradiated with light. After an interface angle forming means making an angleθwhich is formed by the surface of the packed/cured resin on the periphery of the interface between the packed/cured resin generating interfacial peeling during demolding and the mold and expressed on the packed/cured resin side larger than 90°and smaller than 180°, the optical element is demolded.
