An absorbent article (1) having a liquid-retentive absorbing layer (2), a liquid-impermeable leakproof layer (3), and standing gathers (4) on each side thereof which have an elastically extensible portion (40) coming into planar contact with the wearer's skin while worn, wherein the elastically extensible portion (40) is made of a sheet (44) and at least one elastic member (45), the elastic member (45) being fixed to the sheet (44) discretely in the longitudinal direction thereof in their stretched state, and the parts of the sheet where the elastic member (45) is not fixed are raised by contraction of the elastic member (45) to form a plurality of hollow ridges (43) on the side of the elastically extensible portion (40) to be brought into contact with the wearer's skin.
An absorbent article having a liquid-retentive absorbing layer, a liquid-impermeable leakproof layer, and standing gathers on each side thereof which have an elastically extensible portion coming into planar contact with the wearer's skin while worn, wherein said elastically extensible portion is made of a sheet and at least one elastic member, said elastic member being fixed to said sheet discretely in the longitudinal direction thereof in their stretched state, and the parts of said sheet where said elastic member is not fixed are raised by contraction of said elastic member to form a plurality of hollow ridges on the side of said elastically extensible portion to be brought into contact with the wearer's skin in a linear manner along the contraction direction of said elastic member, said hollow ridges each extending across the contraction direction of said elastic member.
An absorbent article having a substantially oblong shape and comprising a liquid-retentive absorbing layer, a liquid-impermeable leakproof sheet, and standing gathers which are provided on each longer side thereof and have an elastically extensible portion coming into planar contact with the wearer's skin while worn, wherein said elastically extensible portion is made of a fiber aggregate containing at least one elastic member and has a large number of ridges formed on its side to be brought into contact with the wearer's skin across the width thereof, said fiber aggregate forming said ridges having a lower density than that forming valleys between every adjacent ridges.
