Description of the Related Art A composite optical element is manufactured by supplying an ultraviolet curable resin to either a mold having an optical surface for forming a desired resin layer or a base material so that the mold and the base material are separated from each other. After forming a desired resin layer between the mold and the base material by pressing and spreading the UV curable resin relatively close to each other, the resin layer is cured by irradiation of ultraviolet rays, and the cured resin layer is removed. This is done by peeling the mold.

題が生じる。When the resin layer is cured by irradiation of ultraviolet rays in such production, the curing rate of the ultraviolet curable resin is 1
Instead of 00%, it is about 70% under the condition of 100 mW / cm 2 and 40 sec. When the curing rate is low, in the heat resistance test, precipitation of uncured components causes a problem that the adhesion of the resin surface to the coating film is lowered and the shape of the resin layer is changed.

いる。However, when a resin in which an ultraviolet curable resin and a thermosetting resin are mixed is used, the resin is irradiated with ultraviolet rays for temporary curing, and after the temporary curing, the resin is molded into a mold. At the same time, it is necessary to heat the material to fully cure it. For this reason, it takes a long time to peel from the mold, which is inferior in mass productivity and requires a large amount of heat including the heat capacity of the mold, which requires a large amount of heating energy.
Further, since a special resin is used, the material cost is high.
