Abstract
In an absorbent article 1 including a liquid-permeable topsheet 2 positioned at a surface that contacts with a human body; a non liquid-permeable backsheet 3 positioned at a surface opposite to the topsheet 2; and an absorbent body 4 provided between the topsheet 2 and the backsheet 3, a three-dimensional gather 6 is formed by a folding portion 32 at which the backsheet 3 is folded up to the topsheet 2 side along both side portions in a longitudinal direction of the absorbent body 4, and a nonwoven fabric at least partially adhered to this folding portion 32. The three-dimensional gather 6 has a free end 62 structured with the nonwoven fabric.
Claims22
An absorbent article comprising:
- a liquid-permeable topsheet positioned at a surface that contacts with a human body;
- a non liquid-permeable backsheet positioned at a surface opposite to the topsheet;
- and
- an absorbent body provided between the topsheet and the backsheet;
- wherein:
- a three-dimensional gather is formed by a folding portion at which the backsheet is folded up to the topsheet side substantially along both side portions in a longitudinal direction of the absorbent body and a nonwoven fabric at least partially adhered to the folding portion;
- and
- the three-dimensional gather has a free end structured with the nonwoven fabric.
