PROBLEM TO BE SOLVED: To obtain a heat resistance of >=180 deg.C by specifying the main component to constitute a high refractive index resin material. SOLUTION: A high refractive index resin material 5 and a low ref ractive index resin material 7 are laminated in the region between two glass plates 6, 8 in such a manner that minute spherical or cylindrical faces are arranged in one dimension or two dimensions on the interface between these two resin materials 5, 7. As for the high refractive index resin material, a resin having a thiol bond (R-S-H) or sulfide bond (R-S-R') or a resin expressed by R'-S-R-S-R- S-R' is used as the main component. In formula, S is sulfur, H is hydrogen, R is one of cyclic unsatd. hydrocarbons, cyclic satd. hydrocarbons, straight-chain unsatd. hydrocarbons, and straight-chain satd. hydrocarbons, and R' is an org. compd. having acryloyl groups, methacryloyl groups, epoxy groups, isocyanate groups, amino groups, acyl groups, carboxyl groups, alkoxysilyl groups or vinyl groups. |
