PROBLEM TO BE SOLVED: To provide a decorative sheet rich in three-dimensional appearance and fabric appearance.SOLUTION: A cloth or a resin-impregnated cloth obtained by impregnating the cloth with a resin liquid mainly composed of a thermosetting resin is inserted between resin-impregnated overlay sheets impregnated with a resin liquid mainly composed of a thermosetting resin, laminated with a core material, and pressed by heating. As the thermosetting resins, a melamine resin is used, and as the core material, a phenolic resin-impregnated sheet or a melamine resin-impregnated sheet is used. When the cloth is inserted, two resin-impregnated overlay sheets are disposed on either of a surface side and a reverse side. In the resin-impregnated overlay sheet, base paper having an impregnation rate which is represented by a mathematical formula 1: impregnation rate (%)=[(post-impregnation weight)-(pre-impregnation weight)/(pre-impregnation weight)]×100, of 260-320% in a basis weight of 18-40 g/mis used. |
