A disposable wearing article having a longitudinal direction and a transverse direction, including: a front waist region; a rear waist region; a crotch region extending between the front and rear waist regions; an annular elastic waist panel including a front waist panel and a rear waist panel joined to each other so as to define the front and rear waist region; a crotch panel joined to the elastic waist panel so as to define the crotch region; an absorbent structure joined to the front and rear waist panels and the crotch panel; and a pair of leg-openings' peripheries lying on both sides in the transverse direction of the crotch region, wherein, in a state that the wearing article is opened out in a flat state after the front and rear waist panels have been disjoined from each other, the front and rear waist panels have inner end edges (18a, 19a) and outer end edges (18b, 19b) respectively spaced apart from and opposed to each other in the longitudinal direction and extending in the transverse direction, the inner end edges of the front and rear waist panels lie closer to the crotch region than the outer end edges of the front and rear waist panels, and the inner end edges of the front and rear waist panels cooperate with lateral edges of the crotch panel extending in the longitudinal direction to define the pair of leg-openings' peripheries, wherein: the crotch panel has a pair of leg sheets extending in the longitudinal direction along the lateral edges (11c, 11d) of the absorbent structure, which leg sheets are elasticised leg sheets provided with a plurality of leg elastics; characterised in that the pair of the leg sheets respectively have inner regions adjoining to the absorbent structure and extending in the longitudinal direction and outer regions on the opposite sides to the inner regions and extending in the longitudinal direction, the outer regions of the respective leg sheets are elastic regions in which the plurality of the leg elastics are attached under tension so as to extend in the longitudinal direction, the inner regions are inelastic regions provided with none of the elastics, and front and rear end portions in the longitudinal direction of the respective leg sheets are joined to the inner end edge of the front waist panel and to the inner end edge of the rear waist panel, respectively, such that, in a state that the front and rear waist panels are joined to each other, the inner regions rise above the absorbent structure along the lateral edges of the absorbent structure in a thickness direction of the absorbent structure, and the outer regions are bent outwardly in the transverse direction so as to define the leg-openings' peripheries. a front waist region; a rear waist region; the crotch panel has a pair of leg sheets extending in the longitudinal direction along the lateral edges (11c, 11d) of the absorbent structure, which leg sheets are elasticised leg sheets provided with a plurality of leg elastics; characterised in that the pair of the leg sheets respectively have inner regions adjoining to the absorbent structure and extending in the longitudinal direction and outer regions on the opposite sides to the inner regions and extending in the longitudinal direction, the outer regions of the respective leg sheets are elastic regions in which the plurality of the leg elastics are attached under tension so as to extend in the longitudinal direction, the inner regions are inelastic regions provided with none of the elastics, and front and rear end portions in the longitudinal direction of the respective leg sheets are joined to the inner end edge of the front waist panel and to the inner end edge of the rear waist panel, respectively,
