PROBLEM TO BE SOLVED: To provide a surface coated woody fiberboard withstanding abrasion sufficiently because coating low in viscosity is pressed and penetrated into a mat body, which is produced by a wet papermaking method, by a roll coater before drying to be applied thereto and can be applied to the surface of the mat body of the woody fiberboard having fine unevenness even in little coating quantity so as to be infiltrated into the mat body, and to provide a coating film layer having abrasion resistance on the surface of the woody fiberboard by applying stable coating to the surface of the fiberboard having fine unevenness on its surface and having a fluffy surface in as little a coating quantity as possible without causing coating irregularity or see-through. SOLUTION: Coating is pressed to the surface of the mat body, which is produced from a woody fiber slurry by a papermaking method and dehydrated, by a roll coater coating machine to be applied thereto and the coated mat body is heated and dried to obtain the surface coated woody fiberboard. The pressing force of the roll coater coating machine is adjusted to 1-10 mm to compress the surface of the mat body and the viscosity of the coating is 29 sec/Fordcup #4 or below.
