An absorbent article that is favorable in the erection stability of gathers and excels in transversal leakage preventing effects. A pair of gathers of an absorbent article has a three-dimensional configuration part. The three-dimensional configuration part is formed so as to construct a hollow. A first junction edge portion is formed on the inward side in the width direction of the absorbent article and a second junction edge portion is provided on the outward side in the width direction of the absorbent article. The first junction edge portion is located on the area of the surface layer on which the absorbent body is disposed. The second junction edge portion, in at least the area where the pair of wings are disposed, is located on the area of the surface layer and/or backside layer more outward in the width direction than the periphery of the absorbent body.

Absorbent article with side gathers

An absorbent article that realizes favorable erection of gathers and excels in transversal leakage preventing effects. There is disclosed a vertically long absorbent article comprising a surface layer with surface sheet (), a backside layer with backside sheet (), an absorbent layer with absorbent body () interposed therebetween and a pair of gathers () formed of a sheetlike member () so as to have a hollow on both the side areas of the surface layer in the longitudinal direction thereof. The pair of gathers () in the state of having a three-dimensional configuration part () wherein the sheetlike member () makes a convex on the external surface side of the absorbent article in the thickness direction thereof are joined to the surface layer and/or backside layer by a junction portion () provided so as to extend in the longitudinal direction of the absorbent article. The three-dimensional configuration part () is provided so as to construct a hollow. The junction portion () includes a first junction edge portion () defining the edge portion of the three-dimensional configuration part () on the inward side in the width direction thereof and a second junction edge portion () defining the edge portion of the three-dimensional configuration part () on the outward side in the width direction thereof. Providing that Lrefers to the length of the three-dimensional configuration part () from the first junction edge portion () to the second junction edge portion () and Lrefers to the inter-junction-edge-portion distance being the distance between the first junction edge portion () and the second junction edge portion (), the ratio thereof, L/Lis 2 or greater.

An individually wrapped absorbent articlecomprising an absorbent articleand a wrapping sheet, said absorbent article having a shape being relatively long in a longitudinal direction having a liquid-pervious top-sheet, a liquid-impervious back-sheet and a liquid-retentive absorbent core, on one hand, and said wrapping sheethaving a shape being also relatively long in the longitudinal direction arranged to cover the back-sheet of the absorbent article, on the other hand, so as to be folded back in the longitudinal direction of the absorbent articleby a predetermined fold length dimension L, respectively, with the top-sheet inside. The wrapping sheetis provided with a first display regionhaving a predetermined length dimension Las measured from one end of the wrapping sheetin the longitudinal direction and the length dimension Lof the first display regionis set to be smaller than the fold length dimension L
