Zusammenfassung:	To provide a stretchable sheet for an absorbent article having an excellent air permeability, blocking resistance and excellent storage stability, and a method for manufacturing the same.SOLUTION: A method for manufacturing a stretchable sheet for an absorbent article of the present invention comprises: a composite nonwoven fabric manufacturing step in which a plurality of melted or softened elastic filaments 3 spun from a plurality of spinning nozzles are brought into contact with one surface of an original nonwoven fabric 4 before solidification of the elastic filaments 3 to obtain a composite nonwoven fabric 5 in which the elastic filaments 3 are fused to one surface of the original nonwoven fabric 4 while being exposed; a surface roughness imparting step of forming unevenness in a non-contact portion itself with the original nonwoven fabric 4 on the surface of the elastic filament 3; and a stretching step of the composite nonwoven fabric 5.SELECTED DRAWING: Figure 5 【課題】通気性に優れ、且つブロッキング耐性を有し保存安定性にも優れる吸収性物品用伸縮シート及びその製造方法を提供すること。【解決手段】本発明の吸収性物品用伸縮シートの製造方法は、複数の紡糸ノズルから紡出された溶融又は軟化状態の複数の弾性フィラメント３を、該弾性フィラメント３の固化前に原反不織布４の一方の面と接触させて、該弾性フィラメント３が該原反不織布４の一方の面に露出した状態で融着した複合不織布５を得る、複合不織布製造工程と、該弾性フィラメント３の表面における該原反不織布４との非接触部自体に凹凸を形成する、表面粗さ付与工程と、該複合不織布５を延伸する工程とを有する。【選択図】図５
