The absorbent core ( 28 ) has a liquid receiving surface directed towards said topsheet ( 24 ), and the absorbent core ( 28 ) is provided with at least one embossing ( 50 ) forming a channel for liquid drainage at said receiving surface. Preferably an acquisition layer ( 40 ) is provided between the topsheet ( 24 ) and the absorbent core ( 28 ). The acquisition layer preferably extends into the embossing ( 50 ), while a resilient absorbent member ( 30 ) is preferably provided between the absorbent core ( 28 ) and the acquisition layer ( 40 ) in the form of stripes arranged longitudinally spaced along the upper longitudinal sides of the channel ( 50 ) formed by the embossing.
