PROBLEM TO BE SOLVED: To obtain an ultraviolet curing resin composition having high reliability in fixing transparent microbeads and adhesion of a substrate, and the like, for example, the composition suitable for flat lens, a method for producing the lens and a back projection type projector screen using the flat lens, to provide a method for curing the resin composition, and to provide a bonded structure. SOLUTION: A transparent cohesive layer 5 to fix and hold the micro glass beads 2 embedded in the layer consists of a UV-curing resin containing at least an acrylic resin having double bonds in the side chains, a photopolymerization initiator and a thermal crosslinking agent. The micro glass beads 2 are embedded in the thermally crosslinked transparent cohesive layer 5 of the UV-curing resin, having proper softness when thermally crosslinked, and then the UV-curing resin is cured by UV-irradiation so as to enhance fixing and holding of the micro glass beads 2 with the transparent cohesive layer 5.
