Abstract
The invention relates to an absorbent article, such as a sanitary towel, diaper or bandage, having an upper layer or topsheet made of a liquid-impermeable material, the topsheet being provided with openings and being intended to lie against the body of the wearer. The invention is mainly characterized in that the openings are located in depressions arranged in the topsheet and in such wall portions of the depressions which, when seen from the mouths of the depressions, form at least a right angle to the plane of the topsheet; and in that the bottoms of the depressions, when projected perpendicularly to the plane of the topsheet, substantially cover the mouths of the depressions in this plane.
