Claims6
An absorbent article comprising:
- a main body portion comprising a liquid-impermeable back sheet, an absorbent body comprising a superabsorbent polymer and pulp, and a liquid-permeable top sheet,
- wherein the main body portion has a longitudinal direction and a width direction which are perpendicular to each other,
- a three-dimensional gather is disposed on each of two sides of the main body portion in the width direction, and extends in the longitudinal direction,
- the three-dimensional gather comprises a gather sheet, an elastic member, and a superabsorbent polymer film with a thickness of 5 μm to 500 μm,
- one end of the gather sheet is bonded with the liquid-impermeable back sheet, and another end thereof is extended outside of the main body portion and folded inward and bonded with the liquid-permeable top sheet,
- the superabsorbent polymer film is located in a space between the gather sheet, which is formed by folding the gather sheet, and
- one end of the superabsorbent polymer film is located at a bottom of a bonding portion between the liquid-permeable top sheet and the gather sheet.
