PROBLEM TO BE SOLVED: To provide, regarding a manufacturing method of a composite board between a plywood, such as a plywood from planted tree, and a woody fiber board, the method that does not cause deformations such as warp and torsion during its manufacture or use. SOLUTION: The manufacturing method of the woody composite board is provided, which can produce the woody composite board A free of warp, torsion and the like with good productivity by laminating a woody fiber board 2, which is adjusted to a thickness of 0.7-4.0 mm and a water content of 5-10 wt.% and has a specific gravity of 0.6-0.9, and a plywood 1 adjusted to a water content of 8-14 wt.% through a molten hot melt adhesive 3 and by pressing, while the coating layer of the hot melt adhesive is in the molten state, this laminate 5 with a roll press to glue integrally.
