The stretchable nonwoven fabric () is bonded in the stretched state to the non-stretchable sheet. The composite sheet () has a contact area ratio of 65% or more and an air permeation resistance of 0.20 KPa&#xb7;s/m or less. By satisfying these numerical requirements, the composite sheet shows excellent sweat absorption properties and air permeability when used as a constituting member of an absorbent article such as a disposable diaper.
