Abstract:
1. An absorbent article comprising a liquid-pervious surface sheet, a liquid-impervious leakage-preventive sheet, and a liquid-retentive absorption body disposed between the surface sheet and the leakage-preventive sheet, wherein said absorption body comprises at least two layers comprising a first absorption layer and a second absorption layer, said first absorption layer comprises a stack of a plurality of hydrophilic sheets and a super-absorbent polymer disposed between the plurality of hydrophilic sheets, the second absorption layer comprises an absorbent core having a mixture of absorbent fibers and a super-absorbent polymer, and a liquid-pervious tissue covering the absorbent core, said second absorption layer being in a shape of an hourglass having a constriction part narrowly constricted in a longitudinal center area of the second absorption layer, said first absorption layer having a width that is larger than a width of said second absorption layer in a longitudinal middle area of the absorbent article, wherein a difference in width of said first absorption layer and said second absorption layer is from 6 mm to 40 mm, said first absorption layer being disposed closer to a skin side of the absorbent article than said second absorption layer, said first absorption layer and said second absorption layer being integrated together by embossing grooves extending from said surface sheet to said first absorption layer and second absorption layer, the super-absorbent polymer in said first absorption layer being spread in regions other than regions of the embossed grooves.
