Abstract
The present invention provides an absorbent article having a composite sheet with a plurality of gathers on an inner surface facing a wearer's body, which fits and adheres comfortably to the wearer's skin. The composite sheet is provided which includes a stretchable non-woven fabric which expands and contracts in at least one direction, a non-stretchable non-woven fabric, a junction which binds intermittently the stretchable non-woven fabric to the non-stretchable non-woven fabric in the stretching direction, and a plurality of gathers which is formed by loosening a unbounded area of the non-stretchable non-woven fabric in a contracted state, and is arranged along a direction intersecting the stretching direction, in which an apex of each gather does not reach the neighboring gather when the gathers lean to one side of the stretchable direction.
