Abstract
A composite sheet which has a low basis weight, can be prevented from breaking during the production of an absorbent article or in use, and is good to the touch. The composite sheet is a sheet formed by bonding a stretch nonwoven fabric to a nonstretch nonwoven fabric with an adhesive. The stretch nonwoven fabric is bonded in a stretched state to the nonstretch sheet. The stretch nonwoven fabric has, on each side, strip-form sparse regions and strip-form dense regions alternately formed. The sparse regions and dense regions on one side are alternately formed in a second direction so that the dense regions on this side do not overlie the dense regions on the other side. The composite sheet has a maximum breaking strength of 20 N/50 mm or higher.
