PROBLEM TO BE SOLVED: To provide a decorative plate having an incombustible property and excelling in surface smoothness, appearance, water resistance, weather resistance and handleability. SOLUTION: The decorative plate is formed by applying impregnation sealer treatment 104 on one side of a fiber reinforced cement plate 102, and forming a surfacer coating film 106, an enamel coating film 108 and a clear coating film 110 on the treated surface. The decorative plate fulfills the following conditions (1)-(3): (1) the fiber reinforced cement plate has a thickness of 3-6.5 mm, an apparent density of 1.4-1.8 g/cm<SP>3</SP>, and the content ratio of pulp which is reinforcing fiber being 5-8 mass%, (2) the sum total of organic solid contents contained in components of the impregnation sealer, components of the surfacer coating film, components of the enamel coating film and components of the clear coating film is 63-130 g per unit area (m<SP>2</SP>) of the fiber reinforced cement plate, and (3) the heating value of the decorative plate is 8 MJ/m<SP>2</SP>or less.
