A stretch sheet 10 including extensible nonwoven fabrics 11 and 12 and a plurality of elastic filaments 13. The elastic filaments 13 are arranged to extend in one direction without intersecting with each other and bonded to the nonwoven fabrics 11 and 12 over the whole length thereof in a substantially nonstretched state. The stretch sheet 10 is produced by taking off a number of molten elastic filaments 13 as spun from spinning nozzles 16 at a predetermined speed while drawing the filaments 13, fusion bonding the elastic filaments 13 to nonwoven fabrics 11 and 12 before the filaments solidify such that the filaments extend in one direction in a non-intersection relation to each other to make a composite 19, and stretching the composite 19 in the extending direction of the elastic filaments 13 to impart stretchability to the composite 19.
A stretch sheet comprising an extensible nonwoven fabric and a plurality of elastic filaments, the elastic filaments being arranged to extend in one direction without intersecting with each other and bonded to the nonwoven fabric in their substantially nonstretched state over their whole length.
