Abstract
An absorbent article (1) having a liquid-retentive absorbing layer (2), a liquid-impermeable leakproof layer (3), and standing gathers (4) on each side. The gathers have an elastically extensible portion (40) coming into planar contact with the wearer's skin while worn. 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 in its 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.
