A disposable diaper (1) is provided with a barrier adapted to prevent body fluid from free flowing in a back-and-forth direction of the diaper so that such barrier (22) can be reliably held in close contact with the wearers skin. The barrier (22) stands in the way of body fluid flowing in the back-and-forth direction of the diaper and the barrier (22) is provided in the form of an assembly of nonwoven fabric strips (41, 42).
