Abstract

A compound lens produced by heating and pressing a semi-cured product of a curable resin composition containing a (meth)acrylate monomer, a non-conjugated vinylidene group-containing compound, and a photo-radical initiator and a transparent substrate arranged so as to be in contact with the semi-cured product in a state in which a molding die is filled with the semi-cured product and the transparent substrate, and obtaining a cured product by allowing the semi-cured product to be thermally polymerized, exhibits an excellent transfer property, a small number of bubble mixtures, and excellent heat resistance and crack resistance.
