1. A disposable wearable article having an elastic sheet stretchable structure in which an elastic sheet is stacked between a first sheet layer and a second sheet layer, and the first sheet layer and the second sheet layer are bonded through joint holes penetrating the elastic sheet or with the elastic sheet interposed therebetween at a plurality of bonded portions arranged at intervals,
wherein a region having the elastic sheet stretchable structure has a stretchable region which contracts in a stretchable direction by a contraction force of the elastic sheet and is stretchable in the stretchable direction, and a non-stretchable region,
a part of the elastic sheet located in the stretchable region is printed with a first design including design elements,
a part of the elastic sheet located in the non-stretchable region is printed with a second design including design elements,
the first design and the second design are the same when the stretchable region and the non-stretchable region are at an elongation at elastic limit, and
a stretchable direction dimension of the design elements of the first design when a stretch rate of the stretchable region is 130% or more is 80% or more of a stretchable direction dimension of the design elements of the first design when the stretchable region is at the elongation at elastic limit.
