PROBLEM TO BE SOLVED: To provide a method for producing a laminated sheet, capable of meeting such a demand that a layer composed of a thermoplastic polymer should be firmly adhered to a polyvinyl alcohol (PVA) film. SOLUTION: This method for producing the laminated sheet comprises laminating a hydrophilic layer C on at least one of surfaces of the layer A composed of the thermoplastic polymer, forming a water thin layer having a thickness of 0.001-20μm on the layer C, and adhering the layer C to the PVA film, or comprises laminating the hydrophilic layer C on at least one of the surfaces of the layer A composed of the thermoplastic polymer and adhering the layer C to the PVA film on which the water thin layer having the thickness of 0.001-20μm is formed.
