Abstract: PROBLEM TO BE SOLVED: To heighten the smoothness of a plate surface scarcely having change of a coating film even when water contents varies by a method wherein a resin is applied on the surface of a hard or medium fiber board, which is made by bringing a coniferous or broad leaved tree plywood or the stock plate material of their veneers through adhesive into an integral body under hot pressure or cold pressure. SOLUTION: To the surface of a stock plate material 2, which is employed from a coniferous tree plywood and has a predetermined thickness, a surfacing material 3, which is made of another hard fiberboard and has a predetermined thickness is bonded through an adhesive by a hot pressing method, for example. In addition, the surface of the surfacing material 3 is coated by a coating film 4 made of urethane resin coating material. Thus, this plywood can have a high smoothness and be produced at low cost. The concrete surface produced by the plywood has a very good smoothness. The adhesion between the surfacing material 3 of the hard fiberboard and the resin coating film 4 is strong.  The component extracted from the stock plate material 2 is shut off by the surfacing material 3 of the fiberboard, resulting in allowing to suppress the uneven coloring due to the poor hardening or decoloring of the concrete surface. Thus, the plywood is optimum for the as-cast use of concrete.
