The present invention relates to a disposable absorbent article, such as a diaper or an incontinence guard, which includes an inner liquid-permeable casing sheet (1), which lies the closest to the wearer's body when the article is in use, an outer liquid-impermeable casing sheet (2), and an absorbent body (3) which is enclosed between the two casing sheets. According to the invention, the absorbent pad (3) includes, at least in the region thereof which forms the crotch part when the article is worn, a hose-like body (5) which is made of a shape-stable material and which is highly permeable to liquid. The hose-like body is positioned centrally and extends in the longitudinal direction of the article and borders on the inner casing layer and is surrounded by absorbent material (4, 6) at least on the side thereof remote from the inner casing sheet.
