PROBLEM TO BE SOLVED: To increase the adhesive strength of a multilayer optical device in which two different optical materials are layered at their interface. SOLUTION: In the multilayer optical device 10, a thermoplastic resin 12 and a UV curing resin 14 are layered at the interface and a region where a thin film 16 is formed and a region where no thin film is formed exist in the interface. Mutual transfer of organic components of resin materials is prevented in the region where the thin film is formed; and the organic components of the resin materials are mutually transferred and melted in the region where no thin film is formed. Accordingly, the multilayer optical device having high adhesive strength can be obtained. COPYRIGHT: (C)2009,JPO&INPIT
