Claim Text:
1. A wearing article having a longitudinal direction and a transverse direction, comprising: a chassis including a skin-facing side, a non-skin-facing side opposite to the skin-facing side, a front waist region, a rear waist region and a crotch region extending between these front and rear waist regions; a liquid-absorbent member having front and rear ends extending across the crotch region into the front and rear waist regions, the liquid-absorbent member including a liquid-absorbing core, the liquid-absorbing core having front and rear ends; and waist elastics contractibly attached to the front and rear waist regions under tension in the transverse direction, wherein: the chassis includes front and rear waist ends extending in the transverse direction and lateral edges extending in the longitudinal direction; and the front and rear waist regions are joined to each other along the lateral edges whereupon a waist-opening is defined by the front and rear waist ends and a pair of leg-openings is defined by the front and rear waist ends respectively adjacent to the crotch region and the crotch lateral edges, wherein: the front and rear waist ends are arranged at a distance from the front and rear ends of the liquid-absorbent structure and this distance dimension is uniform in the front and rear waist regions; a dimension in the longitudinal direction of the liquid-absorbent structure overlapping the front and rear waist regions is in the range of 70 to 98% of a total dimension in the longitudinal direction of the front and rear waist regions; the front and rear waist regions respectively include first regions extending along the front and rear waist ends which first regions define the waist opening and which first regions at least partially overlap the liquid-absorbent structure and the front and rear waist regions further include second regions located between the first regions and the leg-openings and adjacent to the first regions; the first regions are respectively provided with a plurality of first waist elastics extending in the transverse direction contractibly attached under tension to the respective first regions at a distance from the front and rear ends of the liquid-absorbent structure; the front and rear ends of the liquid-absorbent structure are located in the first regions of the front and rear waist regions; the front and rear ends of the liquid-absorbent core are located in the second regions of the front and rear waist regions; and a tensile stress of the first regions is lower than that of the second regions.
