Abstract: An absorber has at least one continuous groove and a back sheet provided on a non-skin side with a plurality of adhesive displacement stoppers, for fixing the absorbent article to underwear. One continuous groove has a shape having two or more portions protruding toward a front of the continuous groove and/or having two or more portions protruding toward a rear of the continuous groove. The continuous groove includes a groove portion, where an imaginary region overlaps the continuous groove, the groove portion having an area of 3% or greater of the region, the groove portion not overlapping a centerline extending in the front-rear direction in plan view. The displacement stopper overlaps an entirety of the continuous groove in the width direction and an entirety of the groove portion in the front-rear direction, or does not overlap the groove portion, in plan view.
