Manufacturing method of laminated wood board

A method for manufacturing a laminated board 1 includes a veneer manufacturing step, a catalyst supplying step, and a bonding step. The veneer manufacturing step includes manufacturing one or more saccharide-containing veneers 4 from a saccharide-containing plant. The catalyst supplying step comprises supplying a multivalent carboxylic acid to the one or more saccharide-containing veneers 4 to obtain one or more catalyst-containing veneers 7. The bonding step includes stacking the one or more catalyst-containing veneers 7 on one or both surfaces of the core material 3, respectively, and then performing thermal compression to bond the one or more catalyst-containing veneers 7 to the core material 3. Each of the one or more saccharide-containing veneers (4) is more easily compressed than the core material (3). 层压木板1的制造方法包括单板制造步骤、催化剂供应步骤和粘结步骤。单板制造步骤包括由含有糖的植物制造一个或多个含糖类单板4。催化剂供应步骤包括将多价羧酸供应至所述一个或多个含糖类单板4，以获得一个或多个含催化剂单板7。粘结步骤包括将所述一个或多个含催化剂单板7分别堆叠在芯材3的一个表面或两个表面上，并随后进行热压缩使所述一个或多个含催化剂单板7与所述芯材3粘结。与所述芯材3相比，所述一个或多个含糖类单板4的
