PROBLEM TO BE SOLVED: To provide a manufacturing method for a woody composite material having a high strength even when the length of a woody material piece is 150 mm or less, and not requiring cost for transportation even when discarded wood is used. SOLUTION: The discarded wood is crushed by a crusher and classified into crushed woody material pieces of a length less than 20 mm, a length of 20-150 mm and a length more than 150 mm, and the crushed woody material pieces of the length more than 150 mm are crushed once more at least. The pieces of the length less than 20 mm are made heat sources of a boiler and the pieces of the length of 20-150 mm are made raw materials of the woody composite material. A steam press using the boiler as a heat source is installed at a place where the crusher is located and the crushed woody material pieces are bonded by molding with heat and pressure.
