摘要： An absorbent article such as a sanitary napkin or incontinence pad has longitudinal side edges, transversal end edges, a fluid permeable topsheet, a fluid impermeable backsheet and an absorbent core located between the topsheet and the backsheet. The absorbent core includes a first absorbent layer having an opening extending therethrough and a fluid flow control structure located between said first absorbent layer and said backsheet. The first absorbent layer has a longitudinal front portion and a longitudinal back portion and a narrow transversal transition located between said front portion and said back portion. The width of the narrow transversal transition is 50-75% of the widest transversal width of the front portion of the first absorbent layer and 20-50% of the longitudinal length of the opening is located in the front portion of the first absorbent layer.
