Abstract
The invention relates to an absorbent article intended for female users, such as a sanitary napkin, or an incontinence guard, having such a shape and size that it may be substantially accommodated in the crotch region of a pair of panties and having a longitudinal direction, a transverse direction and a thickness direction. The article exhibits a liquid-pervious cover layer and a liquid-impervious cover layer and further an absorbent core consisting of at least one absorbent body, arranged between the two surfaces, and wherein a hump is arranged at the liquid-pervious cover layer of the article. The invention is characterized in that the hump is substantially shape permanent in the transverse direction of the article, both in a wet and in a dry state, and to such an extent that the hump (16) is not deformed in the transverse direction, either temporarily or permanently, by the forces acting on the hump during use of the article.
