PROBLEM TO BE SOLVED: To provide a novel light-transmissive board of high strength that maintains a unique lighting atmosphere created by light-transmissive ceramic.SOLUTION: A light-transmissive board X includes a flat plate-form ceramic plate 1 that is entirely or partially light-transmissive and has a surface-treated front surface of any design, a transparent or translucent flat plate-form reinforcing resin plate 3 disposed on a rear surface of the ceramic plate 1, and a transparent or translucent intermediate adhesive layer 2 that bonds together the ceramic plate 1 and the reinforcing resin plate 3. The light-transmissive board has a three-layer structure formed by integrally laminating the ceramic plate 1, the intermediate adhesive layer 2 and the reinforcing resin plate 3. The reinforcing resin plate 3 and the intermediate adhesive layer 2 do not degrade so much the light-transmissive property of the ceramic plate 1, while contributing to enhancing the strength.SELECTED DRAWING: Figure 1 |
