Abstract

The absorbent article includes a chassis, a crotch region, an absorbent body, and an elastic member arranged along a side edge in width direction of the crotch region. The oblong absorbent body arranged in the crotch region includes a first narrow width section, a second narrow width section, a center low rigidity section formed along a center line that halves the absorbent article in the width direction and a pair of lateral low rigidity sections provided at both sides of the center low rigidity section in the width direction with a substantially equal interval. Skin contacting face-side sheets and non-skin contacting face-side sheets 6 and 10 are arranged in the crotch region. The initial tensile strength of the skin contacting face-side sheets is lower than that of the non-skin contacting face-side sheets or that of the chassis 2.

Claims

1. An absorbent body used for an absorbent article, comprising:

a first narrow width section;

a second narrow width section arranged longitudinally spaced from the first narrow width section of the absorbent article;

a center absorbing section arranged between the first narrow width section and the second narrow width section in the longitudinal direction;

a center low rigidity section that is formed along a center line that halves the absorbent body in the width direction; and

lateral low rigidity sections provided at both sides of the center low rigidity section in the width direction with a substantially equal interval;

wherein

the first narrow width section and the second narrow width section have therebetween, in the longitudinal direction, the center absorbing section shaped so that both edges in the width direction protrude to outer sides in the width direction and become wider than the first narrow width section and the second narrow width section.
