Abstract
A method for manufacturing a modified wood prepares a natural wood material containing more than a predetermined amount of a solvent for dissolving two different compounds which chemically react with each other to form an insoluble compound, provides a layer of each of the different compounds inside each of two opposing surfaces of the wood material, causes the different compounds to chemically react with each other within the wood material and fixes the formed insoluble compound in the wood material, whereby the fixation amount of the insoluble compound in the wood can be effectively increased.
