A wearing article making it possible to prevent a dimension in the transverse direction of respective recesses formed on an absorbent structure from being notably reduced even when the front and rear waist regions are disposed with waist elastic members directly or indirectly overlapping with the absorbent structure. The wearing article has a longitudinal direction parallel to a longitudinal center line, a transverse direction parallel to a transverse center line, a skin-facing surface and a non-skin-facing surface opposite to the skin-facing surface, and includes a chassis having a first waist region defined by one of front and rear waist regions and being elastically contractible in the transverse direction, a second waist region defined by another of the front and rear waist regions and a crotch region lying between the front and rear waist regions, an absorbent structure disposed on the skin-facing surface of the chassis and extending in the longitudinal direction across the crotch region into at least the first waist region and recesses disposed on the absorbent structure, the absorbent structure includes a first region defined in the first waist region and the recesses at least partially lying in the first region and extending in the longitudinal direction; and a shape retention panel is disposed on the non-skin-facing surface of the first waist region so that the shape retention panel may indirectly or directly overlap the first region and the recesses as viewed in a thickness direction of the article.

Wearing article

A wearing article including a region in which the wearer's skin is not seen-through other than the existence region of the absorbent structure even when an area of the absorbent structure is relatively small so that the existence region of the absorbent structure may be un noticeable from the outside. A region of the absorbent structure of a diaper overlapping with the first waist region has a dimension in the transverse direction corresponding to 20 to 30% of a dimension in the transverse direction of the first waist region, the first waist region is disposed with a hardly see-through panel overlapping with the absorbent structure and includes a first region in which the chassis, the absorbent structure and the hardly see-through panel are laminated, second regions adjacent on both outsides in the transverse direction of the first region, in which the chassis and the hardly see-through panel are laminated and third regions adjacent on both outsides in the transverse direction of the respective second regions and only the chassis is included; and a differential total luminous transmittance between the first region and the second regions is smaller than a differential total luminous transmittance between the second region and the third region.

Embodiments of this invention provide a disposable wearing article facilitating even an aged person having relatively weak forth to pull a waist-opening periphery in the transverse direction to widen the waist-opening to a desired size, despite this and the waist region should not slip down during use of the wearing article. Waist elastic elements () are stretched in the transverse direction X at a stretch ratio in a range of about 2.5 to about 3.0 and having fineness in a range of about 800 to about 1000 dtex, a dimension between the waist elastic elements () adjacent in the transverse direction X is in a range of about 5.5 to about 6.0 mm and each of waist elastic regions () in which the waist elastic elements () are present has a tensile stress at a moment of 255% stretching in the transverse direction X in a range of about 4.5 to about 6.0N/35 mm and a tensile stress at a moment of 167% stretching in the transverse direction is in a range of about 1.7 to about 2.1N/35 mm.
