Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an aqueous flame-retardant which easily imparts flame retardancy showing outstanding water resistance to a wood at a low cost, a method for making the wood flame-retardant using the flame-retardant by preventing its elution from occurring and a flame-retardant wood obtained by this method. SOLUTION: The aqueous flame-retardant for wood contains (A) an aqueous inorganic flame-retardant comprising a reaction product obtained by heating 1 pt.mol of boric acid, 1 to 5 pts.mol of urea and 0.05 to 1 pt.mol of phosphoric acid at 90 to 160 °C and (B) a silane coupling agent in the boron/silicon mol ratio of 2.5 to 20. The method for making the wood flame-retardant is performed by applying the flame-retardant to the wood. The flame-retardant wood is obtained by treating the wood with the flame-retardant.
