Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method for a board such as a particle board, a soft fiberboard, a semi-hardboard, MDF, a hardboard or an inorganic board which is obtained by hot pressing and excellent in mechanical strength. SOLUTION: In the manufacturing method for a hot-pressed board, an organic polyisocyanate compound is used as a bonding agent. In using the organic polyisocyanate compound (A) as a bonding agent, a catalyst (B) for isocyanurate formation and, if necessary, an active hydrogen group containing compound (C), are added by coating to introduce isocyanurate bonds into the board.
