A disposable wearing article comprising: a chassis which has a longitudinal direction, a transverse direction, a skin-facing side, a non-skin-facing side, a first waist region corresponding to a front waist region, a second waist region corresponding to a rear waist region and a crotch region extending between said first and second waist regions, a liquid-absorbent structure extending across said crotch region into said first and second waist regions and elastic sheets (51, 52) which are respectively provided in said first and second waist regions to be contractible in said transverse direction, wherein: said liquid-absorbent structure has a bottom surface facing said chassis and a skin-facing surface on said skin-facing side opposed to said bottom surface; said elastic sheets comprise a first elastic sheet lying in said first waist region and a second elastic sheet lying in said second waist region; and said first elastic sheet is bonded to said bottom surface of said liquid-absorbent structure and said second elastic sheet is bonded to said skin-facing surface of said liquid-absorbent structure, characterised in that said chassis has first and second end edges (5, 6) provided respectively in said first and second waist regions and extending in said transverse direction and a folded region folded in two layers along said first end edge and, on said skin-facing side, said folded region overlaps and covers a first end of said liquid-absorbent structure. a chassis which has a longitudinal direction, a transverse direction, a skin-facing side, a non-skin-facing side, a first waist region corresponding to a front waist region, a second waist region corresponding to a rear waist region and a crotch region extending between said first and second waist regions, a liquid-absorbent structure extending across said crotch region into said first and second waist regions and elastic sheets (51, 52) which are respectively provided in said first and second waist regions to be contractible in said transverse direction, wherein: said liquid-absorbent structure has a bottom surface facing said chassis and a skin-facing surface on said skin-facing side opposed to said bottom surface; said elastic sheets comprise a first elastic sheet lying in said first waist region and a second elastic sheet lying in said second waist region; and said first elastic sheet is bonded to said bottom surface of said liquid-absorbent structure and said second elastic sheet is bonded to said skin-facing surface of said liquid-absorbent structure, characterised in that said chassis has first and second end edges (5, 6) provided respectively in said first and second waist regions and extending in said transverse direction and a folded region folded in two layers along said first end edge and, on said skin-facing side, said folded region overlaps and covers a first end of said liquid-absorbent structure. said liquid-absorbent structure has a bottom surface facing said chassis and a skin-facing surface on said skin-facing side opposed to said bottom surface; said elastic sheets comprise a first elastic sheet lying in said first waist region and a second elastic sheet lying in said second waist region; and said first elastic sheet is bonded to said bottom surface of said liquid-absorbent structure and said second elastic sheet is bonded to said skin-facing surface of said liquid-absorbent structure, characterised in that said chassis has first and second end edges (5, 6) provided respectively in said first and second waist regions and extending in said transverse direction and a folded region folded in two layers along said first end edge and, on said skin-facing side, said folded region overlaps and covers a first end of said liquid-absorbent structure.
