To prevent a body fluid from leaking not only in the longitudinal direction of a product but also to the lateral direction thereof by sufficiently damming the body fluid even when a large amount of body fluid is produced at a time. (MEANS FOR SOLVING PROBLEMS) In this absorbent article (1A), an absorbent (4) is installed between a liquid permeable front surface sheet (3) and a liquid impermeable rear surface sheet (3) and an intermediate high part (6) increased in thickness to the front surface side is formed in the generally center area of the absorbent (4). Leakage preventive grooves (8) extending in the longitudinal direction of the absorbent article are formed on both sides of a body fluid discharge part area (K) in the area of the intermediate high part (6). The depth of the leakage prevention grooves (8) is 0.5 to 9.0 mm.
