PURPOSE:To contrive to streamline the production work of the decorative board, the basic board of which is made of lower-grade board material such as sheathing roof board, particle board, flake board or the like and, at the same time, the representation of material surface ground of the basic board made of lower- grade board material having the surface, the grain of which is coarse and which has ruggedness, can be realized. CONSTITUTION:Adhesive layer 4 is formed by applying adhesive at least either on the selected region on the outer surface of basic board 1 or one the inner surface of surfacing material, which covers the above-mentioned region and has the characteristic for transmitting and infiltrating adhesive, so as to form smooth surfaced composite outer layer 9 of the adhesive and the surfacing material by covering the surfacing material with the adhesive layer 4 in order to transmit and infiltrate the adhesive through and in the surfacing material. |
