A composite sheet which has a low basis weight, can be prevented from breakingduring the production of an absorbent article or in use, and is good to the touch.The composite sheet (1) is a sheet formed by bonding a stretch nonwoven fabric(2) to a nonstretch nonwoven fabric (3) with an adhesive (4). The stretch nonwovenfabric (2) is bonded in a stretched state to the nonstretch sheet. The stretchnonwoven fabric (2) has, on each side, strip-form sparse regions (21) and strip-formdense regions (22) alternately formed. The sparse regions (21) and dense regions(22) on one side are alternately formed in a second direction so that the denseregions (22) on this side do not overlie the dense regions (22) on the other side.The composite sheet (1) has a maximum breaking strength of 20 N/50 mm or higher.
