Absorbent article

An absorbent article comprising a skin-side permeable top sheet, a non-skin-side impermeable back sheet, and an absorber disposed between the top sheet and the back sheet, the absorbent article having a front-rear direction configured to correspond to a front-rear direction of a body of a wearer and a width direction orthogonal to the front-rear direction,

• wherein the absorber has at least one compressed groove recessed from a skin side to a non-skin side and at least one continuous groove recessed from the non-skin side to the skin side such that a shape recessed from the non-skin side to the skin side of the at least one continuous groove corresponds to a shape recessed from the skin side to the non-skin side of the at least one compressed groove, each shape recessed from the non-skin side to the skin side of the at least one continuous groove being formed with a contour that is substantially the same as the contour of an entire shape recessed from the skin side to the non-skin side of the at least one compressed groove,
• wherein the back sheet is provided on a non-skin side with a plurality of adhesive displacement stoppers, each having a length in the width direction longer than a length in the front-rear direction, at intervals in the front-rear direction, for fixing the absorbent article to underwear,
• wherein the continuous groove extends across a centerline extending in the front-rear direction, extending more than half of a width of the absorber in the width direction, and 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,
• wherein the continuous groove has a groove portion, where an imaginary region overlaps the continuous groove, that has an area of 3% or greater of the imaginary region and that does not include the centerline extending in the front-rear direction in plan view, the imaginary region defined by both a unit length overlapping the continuous groove in the front-rear direction and a same length in the width direction as the absorber,
• wherein at least one displacement stopper of the plurality of adhesive displacement stoppers at least partially overlaps the continuous groove in the width direction and the groove portion in the front-rear direction in plan view,
• wherein the imaginary region has, in plan view, a rectangular shape having two opposite sides having a first length and two different opposite sides having a second length, the first length being equal to a maximum width of the absorber in the width direction, the second length being a same groove width of the continuous groove in the front-rear direction, and
• wherein a predetermined area of the imaginary region that is overlapped by the continuous groove is less than or equal to 30% of a whole area of the imaginary region defined by the rectangular shape in plan view.
