Claim:
A disposable pants-type wearing article having a front-back direction, a vertical direction and a transverse direction being orthogonal to one another, the article comprising: a front waist region and a rear waist region opposed to each other in the front-back direction and a crotch region extending between the front and rear waist regions; joined regions formed by putting flat and joining together the front and rear waist regions along respective side edges of the front and rear waist regions respectively opposed in the transverse direction and extending in the vertical direction; an absorbent structure in the crotch region; a waist-opening and a pair of leg-openings formed by the front and rear waist regions with the crotch region; and leg elastic members extending under tension along respective peripheral edges of the leg-openings, wherein the leg elastic members respectively have inner surfaces configured to face a wearer's skin and outer surfaces opposite to the inner surfaces, at least one of the inner and outer surfaces is bonded to a sheet member included in the-joined regions and the crotch region, and wherein the leg elastic members include a pair of front side leg elastic members extending from the joined regions and along a front portion of the peripheral edges of the leg-openings, and a pair of rear side leg elastic members extending from the joined regions and along a rear portion the peripheral edges of the leg-openings, the front side leg elastic members are isolated from the rear side leg elastic members, and the sheet member extends along the peripheral edges of the leg-openings over ranges in which the leg elastic members extend along the peripheral edges of the leg-openings, wherein the peripheral edges of the leg-openings are curved lines, and the leg elastic members are in a curved state along the curved lines when the wearing article is kept flat under tension in the vertical direction as well as in the transverse direction, and wherein the pair of rear side leg elastic members overlaps the absorbent structure in a thickness direction, and the pair of front side leg elastic members does not overlap the absorbent structure in the thickness direction.
