PROBLEM TO BE SOLVED: To provide a wood flooring which is excellent in flaw resistance, difficult to generate a recessed warpage, excellent in dimensional stability, good in thermal conductivity and suitable for floor heating. SOLUTION: A plywood 1 having dimensional stability to heat is arranged to a central part. A wood fiber board 2 of a high specific gravity is stuck to a front surface of the plywood 1 to improve a surface hardness and flaw resistance. Besides, the wood fiber board 3 is stuck also to a rear surface to balance a shrinkage by those front and rear wood fiber boards 2 and 3 and generation of a recessed warpage is avoided. Further, a decorative veneer 4 to the front surface and backing veneer are stuck respectively to the rear surface to form a thin flooring of 5 to 9 mm in total thickness and a thermal conductivity is improved.
