An absorbent article having a front part (12), a rear part (14) and an intermediate crotch part (13), such as a diaper, an incontinence guard or like article. The article includes an absorbent body (1), a liquid-impermeable bottom sheet (7) joined to the absorbent body, and a top sheet (9) which is free from connection with the absorbent body over a large part of its surface and which lies proximal to the wearer's body when the article is worn, and which top sheet includes an opening (15) which extends from the rear article part into the crotch part, and elastic devices (24, 25) which are fastened to the top sheet in a stretched state and which when contracting from the stretched state cause the part of the top sheet that is not joined to the absorbent body to be distanced from the body. The top sheet (9) includes a further opening (16) which extends from the front part (12) into the crotch part (13). A piece (26) of flexible material extends transversely across the article between the absorbent body (1) and the top sheet (9) within that region of the top sheet that lies between the two openings (15, 16), this piece of flexible material being fastened to the absorbent body and to the top sheet.
