Abstract

An absorbent article includes an absorbent structure. The edge portions in the absorbent structure's middle portion have a first mean pore size, and the central portion in the middle portion of the absorbent structure has a second mean pore size, the first mean pore size being greater than the second mean pore size. The absorbent article can be folded along the longitudinal centre axis so that a part of the article on one side of the longitudinal centre line and a corresponding part of the article on the other side of the longitudinal centre line are brought together to lie against one another at a plane of the longitudinal centre line on the upper surface of the article. The edge portions which have the greater, first mean pore size thereby form an area of the absorbent article that is first wetted during use.
