<p>PROBLEM TO BE SOLVED: To obtain an air permeable and liquid resistant composite sheet suitable to use for a disposable wearing article. SOLUTION: The composite sheet comprises a hydrophobic first plastic film layer 2 for forming its upper surface, a second plastic film layer 5 for forming its lower surface, and a hydrophobic intermediate fiber aggregate layer 3 connected to the layers 2, 5 between the layers 2 and 5. In this case, a plurality of stripes of first flat parts 8 spaces apart in parallel with each other and a sawtooth-like first rising parts 12 formed along edges of the parts 8 are formed on the layer 2, and second flat parts are formed on the layer 5.</p> |
