PROBLEM TO BE SOLVED: To provide a laminated sheet which simultaneously satisfies a nail hole water-stopping property and workability. SOLUTION: The nail hole water-stopping property is ensured by the elongation of a laminated article of a nonwoven fabric layer 2 and a thermoplastic resin layer 1. In this case, for the nonwoven fabric layer 2, ratios of a strength in the larger direction and a strength in the smaller direction are both in a range of 1.0 to 1.5 regarding the tensile strength and the tearing strength in the longitudinal direction and the lateral direction, and both of the elongation percentages in the longitudinal direction and the lateral direction are set to be 50% or higher. Also, for the thermoplastic resin layer 1, both of the elongation percentages in the longitudinal direction and the lateral direction are set to be 50% or higher. Then, on the laminated article, an elongation control layer 4 is laminated, and the load elongation percentages in the longitudinal direction and the lateral direction are set to be 5% or lower at the time of 20 N/cm of the whole of the sheet. Thus, a slipping feeling at the time of working is eliminated.
