PROBLEM TO BE SOLVED: To provide a moisture permeable laminated sheet having excellent weatherability, capable of being used over a long period of time, capable of being suitably used as a cover sheet for an excretions deposit or the like because both of moisture permeability and air permeability are set to a proper range, and capable of being also utilized as a banking cover material on a construction site. SOLUTION: The moisture permeable laminated sheet is a laminate of a porous polyolefin film and a porous thermoplastic resin film other than the porous polyolefin film. The water pressure resistance of the laminate is not less than 980 N/m<2> (10 gf/cm<2> ), the moisture permeability thereof is not less than 300 g/cm<2> /24 hr, and the tensile strength thereof is not less than 49,000 N/m<2> (500 gf/cm<2> ).
