る。In the prior art described above, since the surface layer 4 is formed by repeating the coating and drying of the coating material, it takes a lot of time and the coating thickness is uniform while the bubbles are formed. There is a drawback that it requires skill and experience because it must be prevented. Further, there is a limit in the thickness of the surface layer 4 formed by coating, and the protective function of the design sheet 3 is deteriorated, and the design sheet 3 cannot be seen through in a deep state. In addition, the coating material must be mixed with a light-colored curing agent and accelerator, which lowers the transparency of the design sheet 3. Further, the polyester resin has poor impact resistance, so that cutting, V-groove, etc. However, there was a drawback that the secondary processing of was difficult. It is an object of the present invention to obtain a novel method of manufacturing a decorative board that solves the above-mentioned drawbacks.

Therefore, the conventional coating process is not required, and it can be quickly obtained without requiring skill.
In addition, by selecting the thickness of the acrylic resin plate as the surface plate, it is possible to easily obtain a product with a predetermined thickness, which enhances the protection function of the pattern sheet and allows the surface plate with a thickness to be interposed. By seeing through the design sheet, the design sheet can be seen in a deep state, and the commercial value is increased. In addition, secondary processing such as cutting, grooving, and polishing becomes easy, and it is possible to utilize the product in the field of products that could not be used conventionally.
