[Problem] To ensure the noncombustibility of a noncombustible material by boric acid alone without adding an additive to promote the dissolution of boric acid. [Solution] First， an object 2 to be treated， which serves as the main material of a noncombustible material， is placed in an impregnation tank 1 in which is stored a boric acid aqueous solution. The boric acid aqueous solution is a solution of boric acid dissolved in water without adding an additive to promote the dissolution of boric acid in water. Next， the boric acid introduced into the impregnation tank 1 is furthermore dissolved while raising the temperature of the boric acid aqueous solution under a pressurized environment， whereby the concentration of the boric acid aqueous solution with which the object 2 to be treated is to be impregnated is made higher than the maximum solubility under an atmospheric-pressure environment. Then， the temperature of boric acid aqueous solution， the concentration of which has been raised， is reduced under conditions that maintain a pressurized state at least until the temperature drops to the boiling point under an atmospheric-pressure environment， thereby precipitating the boric acid with which the object 2 to be treated is impregnated.
