Description of the Related Art Heretofore, a laminate having a decorative material adhered to one or both surfaces of a substrate has been used as a ceiling plate, an inner wall material, or an outer wall material. In this laminated board, the surface on which the decorative material is adhered is robust and excellent in durability, but there is a problem that the decorative material is easily peeled off from the substrate due to infiltration of water or the like from the end face, and the edge of the laminated board has a problem. It is known that a cover member having a U-shaped cross section made of an elastic synthetic resin is covered. Further, there has been known a laminated board which has been subjected to an end surface treatment in which a substrate at an end of the laminated plate is removed, a decorative material is bent, and a decorative material is attached to an end surface of the substrate.
