The edge portion where the thickness portion of the decorative sheet for a wooden edge is exposed can also be covered and covered by the decorative sheet adhered to the surface of the wooden base material, and the design is not impaired.

When a decorative sheet is placed on a wooden substrate, these decorative sheets are temporarily wrapped with a masking film from the surface of the decorative sheet so that the edges of the decorative sheets are brought into close contact with no gap. Adhering, after that, if the manufacturing method has a process of mounting the decorative sheet together with the masking film on a wooden substrate and performing a membrane press molding, the decorative sheet is placed on the wooden substrate. Later, the step of temporary fixing can be omitted, and the complexity can be reduced, and at the stage before bonding, the positioning of each decorative sheet can be visually observed, and it is effective when many decorative sheets are bonded. The effect can be obtained.

Further, according to the decorative board of the present invention, two or more kinds of decorative sheets having different colors and patterns are stuck, and the decorative sheet for a kiguchi is also adhered to the kiguchi surface. At the same time, by the above-mentioned membrane press molding, coating is performed three-dimensionally along the surface shape and the like of the wooden base material, and the surface is formed, so that it is possible to obtain a decorative board having a good design. Becomes

In each of the decorative sheets, at least one of two or more types of decorative sheets to be cut in advance is a thermoplastic resin decorative sheet, and at least one other is a wood veneer decorative sheet. Thus, it is possible to obtain a decorative board capable of expressing desired wood quality, and to obtain an effect of further improving the design.
