Abstract:
1. A composite sheet comprising: a stretchable non-woven fabric which expands and contracts in at least one direction, the stretchable non-woven fabric comprising high-density regions and low-density regions arranged alternatively with each other in a stretching direction to allow expansion and contraction of the stretchable non-woven fabric; 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 non-bound area of the non-stretchable non-woven fabric in a contracted state, and is arranged along a direction intersecting the stretching direction, wherein an apex of each gather does not reach the neighboring gather when the gathers lean to one side of the stretchable direction, and the high-density regions and the low-density regions are formed throughout the stretchable non-woven fabric including portions not including junctions.
