Provided is a method for producing a modified wood-based material. Specifically, provided is a method for producing a wood-based material, the method including: 1) a step for causing permeation, into a wood-based material, of a furan derivative resinification solution containing a furan derivative, an inorganic salt that suppresses polymerization of the furan derivative at an ordinary temperature, and an inorganic salt that accelerates polymerization of the furan derivative; and 2) a step for, through heating, polymerizing the furan derivative of the permeated furan derivative resinification solution in the wood-based material.
