摘要：
PROBLEM TO BE SOLVED: To increase air permeability, softness, and bulkiness in an exterior nonwoven fabric.SOLUTION: There are provided: an absorber 56； a liquid impermeable sheet 11 having air permeability covering a reverse side of the absorber 56； and a cover nonwoven fabric 20 covering the reverse side of the liquid impermeable sheet 11. The cover nonwoven fabric 20 is provided with many holes 14 going through both sides in an area overlapping at least the liquid impermeable sheet 11 at intervals, a surface side of edge parts 14e of the holes 14 is warped upward to the surface side. In the area having holes 14 in the cover nonwoven fabric 20, columns of the holes 14 arranged in a back and forth direction at intervals 14y in the front and rear direction narrower than a back and forth direction dimension 14L of the holes 14 are repeatedly formed at prescribed intervals in a width direction WD. Intervals 14x in a width direction of the holes 14 are wider than a back and forth dimension 14L of the holes 14.SELECTED DRAWING: Figure 24【課題】外装不織布における通気性と、柔らかさや嵩高さとをともに向上させる。【解決手段】上記課題は、吸収体５６と、吸収体５６の裏側を覆う通気性を有する液不透過性シート１１と、この液不透過性シート１１の裏側を覆うカバー不織布２０とを備え、カバー不織布２０は、少なくとも液不透過性シート１１重なる領域に、表裏に貫通する孔１４が間隔を空けて多数設けられ、孔１４の縁部１４ｅが表側に反り上がっており、カバー不織布２０における孔１４を有する領域は、孔１４の前後方向寸法１４Ｌよりも狭い前後方向間隔１４ｙで前後方向に並ぶ孔１４の列が幅方向ＷＤに所定の間隔で繰り返し形成されており、孔１４の幅方向間隔１４ｘは、孔１４の前後方向寸法１４Ｌよりも広いことにより解決される。【選択図】図２４
