PROBLEM TO BE SOLVED: To provide a woody plate constituted by sufficiently infiltrating a styrene-butadiene or acrylic type emulsion in a woody fiberboard such as a medium-duty fiberboard or the like or a particle board. SOLUTION: The medium-duty fiberboard with a thickness of 2.7 mm is sliced into two parts in its thickness direction to form two medium-duty fiberboards with a thickness of 1.35 mm and sanding is applied to each of the divided surfaces of the medium-duty fiberboards to form a medium-duty fiberboard 10 with a thickness of 1.0 mm. Next, a styrene-butadiene type emulsion with a glass transition point (Tg) of -47°C, the lowest film forming temperature (MFT) of -47°C, viscosity of 400 mPa s and a surface tension of 33 mN/m is applied to the sanding surface of the medium duty fiberboard 10 with the thickness of 1.0 mm in an amount of 8.0 g/0.994 ft<SP>2</SP>and the coated fiberboard is pressed for 60 sec at 120°C under pressure of 784 kPa by a hot plate to manufacture the woody plate wherein the medium duty fiberboard 10 is impregnated with the styrene-butadiene type emulsion.
