Abstract
The present invention provides an absorbent article 1 that does not easily warp in a leg-surrounding portion. The absorbent article 1 includes an absorbing member 2 in an elongated shape arranged along a longitudinal direction of the absorbent article, and a stretchable chassis 3 having a leg-surrounding portion 3a recessed inward in a width direction. At least a part of the chassis 3 is composed of a composite sheet 13 obtained by affixing a stretchable sheet 15 and a non-stretchable sheet 16 to each other by a plurality of adhesive portions 18. The leg-surrounding portion 3a has an intersection crossing an expansion and contraction direction of the chassis 3 at a predetermined angle. The plurality of adhesive portions 18 extend in a direction substantially perpendicular to the expansion and contraction direction.
