A wood board comprising a core layer comprising one or more strand boards formed by using a foaming binder, and at least one surface layer comprising oriented strand board, which is laminated to at least one surface of the core layer, the foaming binder being a mixture of a foaming resin and a non-foaming resin at a ratio within a range of 4:1-1:4. It is preferable that the thin wooden strips comprising the surface layer has at least one of an average length value and an average width value thereof which is larger than that of the thin wooden strips comprising the core layer. The wood board of the present invention has particularly superior resistance to moisture, and has low density and high strength. In the wood board of the present invention, it is possible to adjust the anisotropy of the strength thereof by adjusting the number of layers or the thickness thereof. The present invention furthermore provides a flooring material having high strength in which a decorative single sheet is applied to at least one surface of the wood board described above.
