Of decorative veneers 2a and 2b and resin sheet 3. The decorative veneers 2a and 2b are veneer-like veneers formed by slicing. The resin sheet 3 is obtained by impregnating a fiber base material with a resin. A resin sheet 3 is superimposed on a thick veneer veneer 2b located below, and a veneer veneer 2a having a small thickness is superimposed on the resin sheet 3 and is heated and pressed by a press. A floor surface material 2 as shown in FIG. 1A is formed. The floor surface material 2 thus formed is cut into an appropriate size, and the periphery is chamfered 4 to form a floor surface material piece 5 as shown in FIG. 1 (b). The chamfer 4 is formed up to the second-layer decorative veneer 2b. A plurality of the floor surface material pieces 5 are arranged and assembled on the same plane, and the floor surface material pieces 5 are adhered to the floor base material 1 such as plywood.
The actual processing and coating are performed as described above to form a floor material A as shown in FIG. 1 (c).
