PROBLEM TO BE SOLVED: To provide a laminated sheet having a high strength, light-weight properties and high sealability. SOLUTION: The sheet is obtained by laminating a woven fabric and a highly sealable film. In this case, yarns for constituting the fabric are each made of a core-sheathing type composite fiber. A core component of the fiber is made of a melt anisotropic aromatic polyester, and a sheath component of the fiber is made of a polyphenylene sulfide. The yarn made of the fiber has a size of 10 to 250 dtex, a strength of 10 cN/dtex or more and an elastic modulus of 350 cN/detx or more. The woven fabric is made of the core- sheathing type composite fibers. The light weight, high strength and sealable sheet is obtained by laminating the fabric and an ethylene vinyl alcohol copolymer film having a thickness of 10 to 40μm.
