A wearing article having a longitudinal direction, and a transverse direction, a skin-facing surface and a non-skin-facing surface, and including a front waist region, a rear waist region and a crotch region extending between the front and rear waist regions wherein the front and rear waist regions are joined to each other to form an annular elastic waist panel, a crotch panel is located in the crotch region so as to extend between the front and rear waist regions and an absorbent structure is located in a central area on the skin-facing surface of the crotch panel, wherein: a pair of elasticized leg sheets extending in the longitudinal direction are joined to respective side edge portions of a base layer as a constituent of the crotch panel; the elasticized leg sheets respectively include side sheets, a first continuous leg elastic element and a second continuous leg elastic element, each of the side sheets being folded back so as to interpose the first and second leg elastic elements (50, 61); and each of the side sheets has a proximal side edge joined to the base layer and extending in the longitudinal direction and a distal side edge facing the proximal side edge and extending in the longitudinal direction and is divided into a joint region extending along the proximal side edge, an elasticized region extending along the distal side edge and a non-elasticized region extending between the joint region and the elasticized region and provided with none of elastic elements, wherein the second leg elastic elements are contractibly arranged under tension in the longitudinal direction along the joint regions of the elasticized leg sheets and the first leg elastic elements are contractibly arranged under tension in the longitudinal direction in the elasticized regions, characterised in that each of the elasticized leg sheets is joined to the base layer in such a state that the side sheet is shrunk together with the first leg elastic element and the second leg elastic element but a stretch ratio of the first and second leg elastic elements (50, 61) is maintained at a value larger than 1 and a number of gathers extending in parallel in the transverse direction are formed in the joint region. a pair of elasticized leg sheets extending in the longitudinal direction are joined to respective side edge portions of a base layer as a constituent of the crotch panel; the elasticized leg sheets respectively include side sheets, a first continuous leg elastic element and a second continuous leg elastic element, each of the side sheets being folded back so as to interpose the first and second leg elastic elements (50, 61); and each of the side sheets has a proximal side edge joined to the base layer and extending in the longitudinal direction and a distal side edge facing the proximal side edge and extending in the longitudinal direction and is divided into a joint region extending along the proximal side edge, an elasticized region extending along the distal side edge and a non-elasticized region extending between the joint region and the elasticized region and provided with none of elastic elements, wherein the second leg elastic elements are contractibly arranged under tension in the longitudinal direction along the joint regions of the elasticized leg sheets and the first leg elastic elements are contractibly arranged under tension in the longitudinal direction in the elasticized regions, characterised in that each of the elasticized leg sheets is joined to the base layer in such a state that the side sheet is shrunk together with the first leg elastic element and the second leg elastic element but a stretch ratio of the first and second leg elastic elements (50, 61) is maintained at a value larger than 1 and a number of gathers extending in parallel in the transverse direction are formed in the joint region.
