PROBLEM TO BE SOLVED: To provide a reflective multilayer body which can be manufactured by using a normal prism sheet and can effectively increases the adhesion strength between protruding walls and the prism sheet without using an emboss joint method easily causing deformation of prism projections. SOLUTION: The reflective multilayer body has a prism sheet which can reflect light by prism projections, a supporting body laminated with the prism sheet, and an adhesive layer disposed between the prism sheet and the supporting body. Protruding walls are fixed to the surface of the supporting body, and the prism sheet and the protruding walls are adhered with the adhesive layer so as to form a space where the prism projections are not in contact with the adhesive layer but exposed. The protruding wall is formed as bonded with the surface of the supporting body and has a base end bonded to the surface of the supporting body along the surface of the supporting body, a top end bonded to the back face of the prism sheet with the adhesive layer, and a wall face connecting the base end and the top end. The adhesive layer is tightly adhered to at least the top end and the wall face of the protruding wall. COPYRIGHT: (C)2004,JPO |
