Abstract
A disposable undergarment includes a pair of elastically stretchable first wings extending outward from transversely opposite side edge portions of a rear waist region, proximal side edge portions of the respective first wings are contiguous to transversely opposite side edge portions of a crotch region. The undergarment further includes a pair of elastically stretchable second wings placed upon the first wings and extending outward from the transversely opposite side edge portions of the rear waist region, proximal side edge portions are not contiguous to the transversely opposite side edge portions of the crotch region. A stretch stress generated in the first wings as the front and rear waist regions are connected to each other is exerted upon the undergarment in a waist-surrounding direction as well as in a thigh-surrounding direction but a stretch stress generated at the same time is exerted upon the article only in the waist-surrounding direction.
