PURPOSE: To provide a lightweight, large-sized facade natural stone board by adhering a ceramic tile having substantially equal thermal expansion coefficient to the reverse side of a thin stone plate, and performing the suspension through a tile on the back. CONSTITUTION: A ceramic tile 8 of 6-8 mm thick having a thermal expansion coefficient substantially equal to that of a stone plate 7 is adhered to the reverse side of the stone plate 7 of 3-4 mm thick through an adhesive 11 (solvent-free binary epoxy resin) to form a large-sized natural stone element 6 of about 1.5×0.5 mm. In suspending this to a structure 3, the ceramic tile 8 is fixed to a clip 2 fixed to the structure 3 by a screw 9. According to this, the stone plate can be reduced in weight, and the mounting work can be facilitated.
