The wood board in accordance with the present invention comprises a core layer 1 comprising a strand board, and a surface layer 2 comprising a oriented strand board which is laminated on at least one surface of the core layer 1; the surface layer 2 comprises thin wooden strands which are thinner than the thin wooden strands comprising the core layer, and furthermore, the flooring material of the present invention is obtained by laminating a decorative single sheet onto at least one of the surface layers 2 of the wood board. The wood board and flooring material in accordance with the present invention have high strength and superior surface smoothness. Furthermore, if a specified water-repelling agent is added to the binder which is used in molding, it is possible to obtain a wood board having superior water resistance.
