The present invention provides a wearing article that the wearer's buttocks should not be at least partially exposed to the outside and the leg-openings are kept in close contact with the wearer's body at a desired fit so that leakage of body exudates may be reliably prevented and a manufacturing process for such wearing article. A wearing article (10) includes a front waist panel (18), a rear waist panel (19) and a crotch panel (13) having an absorbent structure (11) wherein respective inner end edges (18a, 19a) of the front and rear waist panels cooperate with both side edges of the crotch panel extending in a longitudinal direction to define peripheries (23) of a pair of leg-openings. The crotch panel is provided with a pair of elasticized leg sheets (43) joined to both side edges of the absorbent structure and extending in a longitudinal direction. Each of the elasticized leg sheets having a non-elasticized region (57a) adjacent to the absorbent structure and an elasticized region (57b) adjacent to the non-elasticized region so that the non-elasticized region rises along the associated side edge of the absorbent structure to the associated leg-opening and the elasticized region extends outward in a transverse direction of the wearing article so as to form the associated leg-opening.
