An absorbent article having an absorber that absorbs excrement, the absorbent article comprising an elastic film stretchable structure in which an elastic film is stacked between a first sheet layer and a second sheet layer, wherein the elastic film has plurality of through holes arranged at intervals, the first sheet layer and the second sheet layer are joined through the through holes penetrating the elastic film at a plurality of sheet bond portions, the plurality of sheet bond portions are arranged within the through holes, wherein a region having the elastic film stretchable structure includes a stretchable region stretchable in one direction and a non-stretchable region provided at least at one side of the stretchable region in a stretching and contracting direction, the stretchable region has a section in which the elastic film linearly continues along the stretching and contracting direction, the stretchable region is contracted in the stretching and contracting direction by a contraction force of the elastic film while it is possible that the stretchable region is stretched in the stretching and contracting direction, and the non-stretchable region, due to presence of the through holes, does not have a section in which the elastic film linearly continues along the stretching and contracting direction, even though the elastic film of the non-stretchable region continues in the stretching and contracting direction.
