An absorbent article comprising a main body including a liquid-permeable topsheet , a liquid-impermeable backsheet , and an absorbent body disposed between the topsheet and the backsheet , wherein the main body has an elongated shape with a predetermined length in a front-rear direction and a predetermined width in a width direction orthogonal to the front-rear direction, the main body having a middle region (M) including a body fluid discharge opening corresponding region that corresponds to a body fluid discharge opening of a wearer when attached, a front end region (F) forward of the middle region, and a rear end region (R) rearward of the middle region (M), the main body having a compressed groove recessed from a topsheet side to a backsheet side, wherein the compressed groove includes: a pair of front-rear direction compressed grooves extending in the front-rear direction; and an end region compressed groove formed in at least one of the front end region (F) and the rear end region (R), and having a shape including a substantial V-shape projecting toward the body fluid discharge opening corresponding region , wherein the front-rear direction compressed grooves each have a portion extended beyond a tip of the substantial V-shape of the end region compressed groove in a direction away from the body fluid discharge opening corresponding region , and the portions extended beyond the tip of the substantial V-shape of the end region compressed groove are formed closer to the front-rear direction centerline (CL) toward their end edges . wherein the main body has an elongated shape with a predetermined length in a front-rear direction and a predetermined width in a width direction orthogonal to the front-rear direction, the main body having a middle region (M) including a body fluid discharge opening corresponding region that corresponds to a body fluid discharge opening of a wearer when attached, a front end region (F) forward of the middle region, and a rear end region (R) rearward of the middle region (M), the main body having a compressed groove recessed from a topsheet side to a backsheet side, wherein the compressed groove includes: a pair of front-rear direction compressed grooves extending in the front-rear direction; and an end region compressed groove formed in at least one of the front end region (F) and the rear end region (R), and having a shape including a substantial V-shape projecting toward the body fluid discharge opening corresponding region , a pair of front-rear direction compressed grooves extending in the front-rear direction; and an end region compressed groove formed in at least one of the front end region (F) and the rear end region (R), and having a shape including a substantial V-shape projecting toward the body fluid discharge opening corresponding region , wherein the front-rear direction compressed grooves each have a portion extended beyond a tip of the substantial V-shape of the end region compressed groove in a direction away from the body fluid discharge opening corresponding region , and the portions extended beyond the tip of the substantial V-shape of the end region compressed groove are formed closer to the front-rear direction centerline (CL) toward their end edges . <EOS>
