It is made of a sheet or a sheet obtained by laminating two or more kinds or a waterproof or flame retardant treatment. The core material 3 is made of a synthetic resin foam such as a polyurethane foam, a polyisocyanurate foam, a phenol foam, a vinyl chloride foam, a polyethylene foam, a polystyrene foam, and a urea foam. If necessary, a resol-type phenol stock solution, a curing agent, and a foaming agent are mixed, and the mixture is discharged onto the back side of the front surface material 1 or the back surface material 2 and heated to react, foam, and cure. It is. In the core material 3, light-weight aggregates (pearlite grains, glass beads, gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.) and fibrous materials (glass wool, rock wool, carbon fiber, (E.g., graphite) to improve fire resistance and fire resistance. Of course, an inorganic material such as rock wool, glass wool, ceramic wool or the like may be used as the core material 3. The male connecting portion 4 has a bottom surface 7 protruding outward from a tip of a side wall 6c formed at one end of the embossed pattern decorative surface 6, and
An upper surface 8 having a tip of the bottom surface 7 bent inward and a tip projecting inward, a locking piece 9 formed from the bottom surface 7 and the upper surface 8,
The upper surface 8 is formed by a fitting piece 10 having a tip bent inward and a tip projected outward, and an engagement groove 11 formed by the upper face 8 and the fitting piece 10. The female connecting portion 5 has a locking groove 12 formed by bending the tip of a side wall 6d formed at the other end of the embossed pattern decorative face 6 inward and projecting the tip outward, and a lower edge of the locking groove 12. 13, an upper edge 14 having a distal end bent inward and a distal end projecting inward, an engagement piece 15 formed by the lower edge 13 and the upper edge 14, and an upper edge 1
