PROBLEM TO BE SOLVED: To provide a laminated sheet using a material having good biodegradability and having sufficient gas barrier properties. SOLUTION: The laminated sheet comprises a paper substrate and a coating layer laminated on one surface side of the paper substrate， in which the coating layer has a layer containing cellulose nanofibers as a main component and a layer containing polyvinyl alcohol as a main component， in which the content of polyvinyl alcohol in the solid content of the layer containing polyvinyl alcohol as a main component is 80 mass% or more， and the total amount of coating as the solid content of the layer containing polyvinyl alcohol as a main component is 4 g/m 2 to 10 g/m2. The oxygen permeability is preferably 8，000 cc/m2*24 hr*atm or less.SELECTED DRAWING: Figure 1
