PROBLEM TO BE SOLVED: To prevent the deformation of a second resin due to the effect of cure shrinkage of a first resin when integrating the first resin and the second resin by laminating them. SOLUTION: A molding method has a step for supplying an ultraviolet curable resin 15, a step for curing the ultraviolet curable resin 15, a step for supplying a thermoplastic resin on an optical surface of the ultraviolet curable resin 15, and a step for curing the thermoplastic resin. The shrinkage ratio of the ultraviolet curable resin 15 is larger than that of the thermoplastic resin, and the transition point of glass of the ultraviolet curable resin is preferably higher than that of the thermoplastic resin.
