A water-vapor-permeable waterproof composite fabric having high flexibility, water pressure resistance and water laundering resistance is constituted from a substrate fabric and a polyether-ester elastomer (PEE-A) film layer laminated to the substrate fabric through a polyether-ester elastomer (PEE-B) binder layer, each of PEE-A and PEE-B including polyalkylene glycol residues, alkyleneglycol residues and dicarboxylic acid residues, in which composite fabric, (1) the PEE-A contains 5 to 25% by mass of polyethyleneglycol residues, (2) the PEE-A film layer is 5 to 5 μm thick, (3) the PEE-B has a melting temperature of at least 20° C. below that of the PEE-A and (4) the PEE-B binder layer is present in an amount of 2 to 20 g/m 2 . |
