PROBLEM TO BE SOLVED: To provide a high precision optical element producing technique which eliminates the dispersion of the amount of an injected resin by the remaining of a semi-cured resin and the nonuniformity of resin polymerization curing and is good in continuous molding properties. SOLUTION: The optical element producing technique including a process in which an energy curable resin (11) is packed in a cavity (6) formed in a mold and cured by being irradiated with energy rays from the outside of the cavity (6) has a process in which the resin (11) is injected into the cavity (6) through a resin injection path (8) constituted of an energy ray shading member, a process in which the shading member (9) is moved to cut off a route ranging from the resin injection path (8) to the cavity (6), and a process for irradiating the resin (11) in the cavity (6) with the energy rays.
