PROBLEM TO BE SOLVED: To provide a ligneous material hard to produce formaldehyder by the decomposition of an initial compound according to a change in a use environment or fluctuations in temperature and humidity when the ligneous material such as plywood, a ligneous board or the like is used as the interior material of a terminal consumer's house and not bringing about a sick house syndrome in a resident. SOLUTION: This formaldehyde absorbent for the ligneous material contains ethylene/urea derivatives, especially preferably an ethylene/urea aqueous solution and a surfactant. In the ligneous material processing method, the formaldehyde absorbent is applied to or impregnated with the ligneous material. COPYRIGHT: (C)2005,JPO&NCIPI
