Abstract
An absorbent article has two side edges (9, 10), two end edges (11, 12), a liquid-permeable surface layer (2), a liquid-tight surface layer (3), and an absorption body (4) arranged between the surface layers (2, 3). The absorption body (4) includes at least one intermediate storage part (22–25) arranged along a side edge (9, 10), in direct contact with a liquid transfer part (26). The liquid transfer part (26) has a higher liquid affinity than the intermediate storage layer, so the liquid transfer layer drains from the intermediate storage part (22–25) better than the intermediate storage part (22–25) drains liquid from the liquid transfer part (26).
