PROBLEM TO BE SOLVED: To provide something which can produce a decorative plate in which no deformation including warpage and torsion occurs during production and use, and the through knot of plywood and the trace of a hard late wood part do not float on the surface during production in good productivity with respect to the decorative plate in which a decorative layer is formed on the surface of a woody composite board in which plywood such as forested tree plywood and a woody fiberboard are compounded, and its production method. SOLUTION: The decorative plate with the occurrence of deformation including warpage and torsion prevented during use is composed of a moisture-proof surface decorative layer, the woody fiberboard having a thickness of 4.0 mm or below and an air drying specific gravity of 0.6-0.9, a high moisture-proof hot-melt resin adhesive layer having a moisture-proof performance of at least 30 g/m<SP>2</SP>×24 h in a test according to JIS Z0208 condition B, and plywood which are arranged in turn from above. In a method for producing the decorative plate, the decorative plate can be produced in good productivity while deformation including warpage and torsion is prevented during production, and the through knot and the trace of the hard late wood part do not float on the surface.
