Abstract:
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 (2), a backside layer with backside sheet (3), an absorbent layer with absorbent body (4) interposed therebetween and a pair of gathers (5,5) formed of a sheetlike member (9) so as to have a hollow on both the side areas of the surface layer in the longitudinal direction thereof. The pair of gathers (5,5) in the state of having a three-dimensional configuration part (10) wherein the sheetlike member (9) 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 (11) provided so as to extend in the longitudinal direction of the absorbent article. The three-dimensional configuration part (10) is provided so as to construct a hollow. The junction portion (11) includes a first junction edge portion (10a) defining the edge portion of the three-dimensional configuration part (10) on the inward side in the width direction thereof and a second junction edge portion (10b) defining the edge portion of the three-dimensional configuration part (10) on the outward side in the width direction thereof. Providing that L1 refers to the length of the three-dimensional configuration part (10) from the first junction edge portion (10a) to the second junction edge portion (10b) and L2 refers to the inter-junction-edge-portion distance being the distance between the first junction edge portion (10a) and the second junction edge portion (10b), the ratio thereof, L1/L2 is 2 or greater.
