The present invention provides an absorbent article having an excellent effect of preventing liquid leakage by a leak-proof cuff. A leak-proof cuff (5) is configured to include a leak-proof cuff sheet (6). And an upright portion 51 that stands upright. In each of the front portion F and the rear portion R, an upright inhibiting portion 55 is formed in which the edge 52a side of the upright portion 51 is fixed to another member (top sheet 2) located on the non-skin side of the edge portion 52a. Have been. The absorber 4 has a rear slit region RS in the rear portion R in which a plurality of rear slits R1 extending in the lateral direction Y are arranged. The upright obstruction portion 55 of the front portion F is located ahead of the front folding curve FL in the vertical direction X, and the upright obstruction portion 55 of the rear portion R is located at the same position or the same region RS as the rear slit region RS in the vertical direction X. It exists behind the vertical direction X.
