Abstract:
1. A disposable wearing article having a longitudinal direction and a transverse direction being orthogonal to the longitudinal direction, comprising a chassis having a skin-facing side, a non-skin-facing side, a front waist region, a rear waist region and a crotch region extending between the front and rear waist regions, and a liquid-absorbent structure extending across the crotch region into the front and rear waist regions, wherein: the chassis has an inner sheet lying on the skin-facing side and an outer sheet lying on the non-skin-facing side; the article further comprises waist elastic elements sandwiched between the inner and outer sheets to extend along a waist-opening periphery of the chassis in the transverse direction; the waist elastic elements are bonded to the chassis while being stretched in the transverse direction at a stretch ratio in a range of about 2.5 to about 3.0 and have fineness in a range of about 800 to about 1000 dtex; a spacing dimension between the waist elastic elements adjacent in the longitudinal direction is in a range of about 5.5 to about 6.0 mm; and an annular waist elastic region in which the waist elastic elements are present has a tensile stress at 255% elongation in the transverse direction in a range of about 4.5 to about 6.0N/35 mm and a tensile stress at 167% elongation in the transverse direction in a range of about 1.7 to about 2.1N/35 mm.
