PROBLEM TO BE SOLVED: To provide, at low cost, a flooring laminated with a decorative sheet excellent in surface smoothness, surface hardness, dimensional stability, and stability against warpage and torsion, excellent in adhesive property with a substrate, excellent in working efficiency, and enabling the easy quality control in manufacturing steps. SOLUTION: In this flooring, a decorative material formed of a thermoplastic synthetic resin sheet is laminated on the surface of a wooden base material. A projection and a recess fitted to the projection are formed on and in the side surfaces of the wooden base material. The wooden base material is formed of a base which is composed of a surface layer made of a middle specific gravity fiberboard and a laminate of wooden veneers supporting the surface layer. The laminate is so formed of even number of wooden veneers that the direction of the wood fibers cross perpendicular to each other. COPYRIGHT: (C)2007,JPO&INPIT
