A method of producing a wood-based material that is modified is provided. Specifically, there is provided a method of producing a wood-based material, comprising 1) a step of impregnating a wood-based material with a furan derivative resinification solution that comprises a furan derivative, an inorganic salt inhibiting polymerization of the furan derivative at normal temperature, and an inorganic salt accelerating polymerization of the furan derivative; and 2) a step of polymerizing the furan derivative in the furan derivative resinification solution impregnated into the wood-based material within the wood-based material by means of heating.
