Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of manufacturing a board capable of providing the board small in boiling mass reduction rate and excellent in water resistance without deteriorating flexure strength when the board is manufactured by using a polyvalent carboxylic acid and saccharides as additives.SOLUTION: A method of manufacturing a board includes following processes (A) and (B). (A) a process for dispersing polyvalent carboxylic acid, saccharide, and ammonium sulfate in an aggregate of ligneous small piece; (B) a process for obtaining the board to which the ligneous small piece is adhered by thermal pressing the aggregate of the ligneous small piece in which the polyvalent carboxylic acid, the saccharide and ammonium sulfate are dispersed.SELECTED DRAWING: None
