PROBLEM TO BE SOLVED: To improve a 180 deg. releasing strength of a decorative sheet when the sheet constituted of a polyolefin resin or particularly the sheet constituted by further laminating a surface protective layer on a doubling sheet using two polyolefin resin sheets is adhered to another base material. SOLUTION: A hardness of a polyolefin resin sheet of a front surface side (observing side) and a thickness of a surface protective layer of two polyolefin resin sheets are specified. A universal hardness of the sheet of the front surface side before laminating of the two sheets for constituting the laminated sheet made of the laminated sheet having at least one of the two sheets laminated by an adhesive layer of a polyolefin resin sheet and a surface protective layer further laminated at the front surface side is 30 to 100 N/mm2, and a thickness of the protective layer is 1 to 6μm.
