A laminate sheet comprising (A) a polyester block copolymer which comprises 20 to 70 wt % of a hard segment consisting of an aromatic polyester and 80 to 30 wt % of a soft segment consisting of an aromatic polyester and (B) cloth on at least one side of which the polyester block copolymer is laminated, the melting point (T,.degree. C.) of the polyester block copolymer satisfying the following expressions: T0-5 >T>T0-60 and T>T'+10 (in which T is defined above, T0 is a melting point (0.degree. C.) of the aromatic polyester constituting the hard segment, and T' is a melting point (.degree. C.) of a random polymer obtained by adding 0.1 wt % of titanium tetrabutoxide to the polyester block copolymer and melting and kneading at 250.degree. C. for 3 hours).
