Abstract
In an absorbent product, an absorbent core includes an upper absorber including a super absorbent material fixedly attached between upper and lower absorber sheets. The upper absorber includes material existence regions that are arranged in the width direction and to which the super absorbent material is fixedly attached, and a material non-existence region in which the super absorbent material does not exist is arranged between each pair of adjacent material existence regions. In each material non-existence region, the upper and lower absorber sheets are entirely joined together. In at least one material non-existence region, the top sheet and the upper absorber sheet are partly joined together. The load applied when the nonwoven fabric of the top sheet is stretched 3% in the width direction is twice or more of the load applied when the nonwoven fabric of the upper absorber sheet is stretched 3% in the width direction.
