Abstract
A stretchable structure of an absorbent article includes two sheet layers that extend in a stretchable direction and an orthogonal direction orthogonal to the stretchable direction; and elongated resilient and elastic members that are disposed between the sheet layers at predetermined intervals in the orthogonal direction and extend in the stretchable direction, wherein, the two ends in the stretchable direction of each of the resilient and elastic members comprise fixed ends fixed to the two sheet layers, and the section between the fixed ends comprises a free section unfixed to the two sheet layers, at least one sheet bonding section is disposed in at least one inter-free region defined between the free sections adjacent to each other in the orthogonal direction, the two sheet layers being bonded in the at least one inter-free region, and the two sheet layers in a contracted state conform with each other in a wave pattern in response to contraction of the resilient and elastic members.
