Abstract
The invention relates to an absorbent article, such as diaper, an incontinence protector or the like. In order to prevent urine from being mixed with faeces in the rear area of the article, an essentially liquid impermeable membrane is laid between an inner cover layer and an absorbent layer laying outside of it. The article has an opening to a pocket lying outside the membrane to make possible transport of urine from a front wetting area of the article to a rear area of the absorbent body which lies outside the membrane.
