(Object) To prevent leakage of body fluids and to readily transmit pressure from both sides to a center portion in a width direction by bringing an absorbent article into close contact with a crotch area extending from a body fluid discharge portion to a start position of the intergluteal cleft. (Means of Achieving the Object) A pair of right and left compressed grooves (8, 8) that extend in an approximately longitudinal direction is formed on a surface of a liquid permeable top sheet (3). The compressed grooves (8) have separation distance reduced regions (11), in which a separation distance between the right and left compressed grooves is reduced, formed at the back of a region corresponding to a body fluid discharge portion (H) of a wearer, and also have vastly enlarged portions (10), in which widths of the compressed grooves (8) are enlarged, formed at positions within the separation distance reduced regions (11) and where the separation distance between the right and left compressed grooves (8, 8) becomes minimum.
