PROBLEM TO BE SOLVED: To provide a method for inexpensively and stably producing a high- quality board in good efficiency by which the board can be produced without causing a line trouble or the like caused by the adhesion of a reaction product of an organic isocyanate compound in a pipe when using an organic polyisocyanate-based adhesive. SOLUTION: This method for producing a formed board of a lignocellulose by using (A) an organic isocyanate compound and (B) an active hydrogen compound comprises mixing the component A regulated so as to have <=200μm average particle diameter, with the lignocellulose. As a result, an efficient production is enabled because the adhesion of the polymer of the organic isocyanate compound to a mixing apparatus, a pipe or the like, which can not be avoided in a conventional process for producing the formed board of the lignocellulose by using an isocyanate-based binder, is eliminated.
