<P>PROBLEM TO BE SOLVED: To provided a woody material treatment composition which enhances the hardness, fire retardant properties or the like of a woody material such as wood or the like and making it difficult to pose the problem such as warpage, whitening or the like of the woody material after treatment, a woody material treatment method using it and the woody material treated using the woody material treatment method and excellent in dimensional stability and shape stability. Ž<P>SOLUTION: The woody material treatment composition is obtained by adding at least 50-250 g of diammonium hydrogenphosphate [(NH<SB>4</SB>)<SB>2</SB>HPO<SB>4</SB>], 50-250 g of diphosphoric acid (H<SB>4</SB>P<SB>2</SB>O<SB>7</SB>), 5-30 g of aluminum hydroxide [Al(OH)<SB>3</SB>], 3-15 g of colloidal silica and 10-50 g of a cement supernatant fluid to 1,000 ml of water. The woody material treatment method containing the process for infiltrating the woody material treatment composition and the woody material obtained by performing treatment using this treatment method are also disclosed.
