A wearing article having a longitudinal direction and a transverse direction, the wearing article comprising: a chassis comprising a side facing the wearer's body, a side facing the article wearer's garment, a front waist region, a rear waist region and a crotch region extending between the front and rear waist regions; a liquid-absorbent structure extending across the crotch region into the front and rear waist region; and waist elastic members attached to the front and rear waist regions under tension and in a contractible manner in the transverse direction wherein the liquid-absorbent structure includes a liquid-absorbent core, a cover sheet used to cover the core and front and rear end flaps lying outside front and rear ends of the core as viewed in the longitudinal direction and formed of the cover sheet, wherein: the liquid-absorbent structure overlapping the front and rear waist regions has a dimension in the transverse direction corresponding to 70 to 90% of a dimension in the longitudinal direction of respective the front and rear waist regions and the front and rear waist regions extend from a waist-opening end to the side of the crotch region and at least include first regions at least partially overlapping the front and rear end flaps and second regions extending adjacent the first regions; and the first regions are elasticized over the entire area thereof by first waist elastic members in the transverse direction, the second regions respectively include inelastic zones overlapping the core and elastic zones lying outside the inelastic zones outside as viewed in the transverse direction and elasticized by second waist elastic members wherein tightening force of the first regions are set to be lower than that of the second regions, and wherein said tightening force of said first region in said rear waist member is lower than that in said front waist member. a chassis comprising a side facing the wearer's body, a side facing the article wearer's garment, a front waist region, a rear waist region and a crotch region extending between the front and rear waist regions; a liquid-absorbent structure extending across the crotch region into the front and rear waist region; and waist elastic members attached to the front and rear waist regions under tension and in a contractible manner in the transverse direction wherein the liquid-absorbent structure includes a liquid-absorbent core, a cover sheet used to cover the core and front and rear end flaps lying outside front and rear ends of the core as viewed in the longitudinal direction and formed of the cover sheet, wherein: the liquid-absorbent structure overlapping the front and rear waist regions has a dimension in the transverse direction corresponding to 70 to 90% of a dimension in the longitudinal direction of respective the front and rear waist regions and the front and rear waist regions extend from a waist-opening end to the side of the crotch region and at least include first regions at least partially overlapping the front and rear end flaps and second regions extending adjacent the first regions; and the first regions are elasticized over the entire area thereof by first waist elastic members in the transverse direction, the second regions respectively include inelastic zones overlapping the core and elastic zones lying outside the inelastic zones outside as viewed in the transverse direction and elasticized by second waist elastic members wherein tightening force of the first regions are set to be lower than that of the second regions, and wherein said tightening force of said first region in said rear waist member is lower than that in said front waist member. the liquid-absorbent structure overlapping the front and rear waist regions has a dimension in the transverse direction corresponding to 70 to 90% of a dimension in the longitudinal direction of respective the front and rear waist regions and the front and rear waist regions extend from a waist-opening end to the side of the crotch region and at least include first regions at least partially overlapping the front and rear end flaps and second regions extending adjacent the first regions; and the first regions are elasticized over the entire area thereof by first waist elastic members in the transverse direction, the second regions respectively include inelastic zones overlapping the core and elastic zones lying outside the inelastic zones outside as viewed in the transverse direction and elasticized by second waist elastic members wherein tightening force of the first regions are set to be lower than that of the second regions, and wherein said tightening force of said first region in said rear waist member is lower than that in said front waist member.
