Abstract
A wearing article having a waist-opening that can be easily folded back along a fold line extending in a transverse direction without increasing the stiffness in the vicinity of the waist-opening. A diaper includes front and rear waist members and a crotch member. A liquid-absorbent structure of the crotch member is formed outboard of in a longitudinal direction of a core with front and rear flaps exclusively composed of an absorption surface wrapping sheet, a leakage-barrier sheet and a bottom surface wrapping sheet. The front and rear waist members include first regions overlapping the front and rear flaps, respectively, second regions lying adjacent to the associated first regions and third regions lying adjacent to the associated second regions. The front and rear waist members are provided with the first, second and third waist elastics attached between respective inner and outer sheets in the first, second and third regions, respectively. A tensile stress of the first regions and the third regions is adjusted to be lower than that of the second regions.
