Abstract
An object of the present invention is to provide a layered sheet having improved mechanical properties and excellent interlayer adhesion. The object can be fulfilled by a layered sheet formed by layering a modified-polyolefin layer (3), a copolymerized polyamide layer, (4), and a thermoplastic polyurethane-based resin layer (5) in this order on at least one surface of a cloth layered sheet (2) formed by layering a plurality of cloths comprised of thermoplastic resin strands or a layered sheet formed by layering a modified-polyolefin layer (3), a copolymerized polyamide layer, (4), and a polyamide-based resin layer (6) in this order on at least one surface of a cloth layered sheet (2) formed by layering a plurality of cloths comprised of thermoplastic resin strands.
