Abstract
An absorbent article includes a liquid-permeable top layer, a liquid-impermeable back layer, and a liquid-retentive absorbent member interposed between the top layer and the back layer. The absorbent member is arranged such that a pair of absorbent barrier cuffs having a prescribed width are formed at respective left and right opposing side portions of the top layer in the width-wise direction thereof, and liquid-shrinkable members, which can elastically shrink upon absorption of liquid, are disposed within the barrier cuffs and extend in the longitudinal direction of the barrier cuffs.

An absorbent article comprising:
- a liquid-permeable outermost, skin-contactable top layer, a liquid-impermeable back layer, and a liquid-retentive absorbent member;
- said top layer is secured to said liquid-impermeable back layer and said liquid-retentive absorbent member is interposed between said top layer and said back layer;
- said absorbent member includes an absorbent sheet having a thickness of 0.3 mm to 5.0 mm, an entire surface of said absorbent sheet being overlaid with said top layer;
- and
- only the edge portions of said absorbent member and the portions of said top layer overlying said edge portions are integrally folded inwardly toward a center of said absorbent member and outwardly away from the center of the absorbent member to form an opposing pair of absorbent barrier cuffs having an overlapping, serpentine configuration, and which extend along respective longitudinal edge portions of the absorbent article, said back layer and a remaining portion of said absorbent member being oriented in a un-folded state.
