1. A disposable wearing article having a longitudinal direction, a transverse direction extending orthogonally to the longitudinal direction, said disposable wearing article comprising:
a skin-facing side; a non-skin-facing side; a front waist region; a rear waist region; and a crotch region extending between the front and rear waist regions, and including an elastic waist panel defining the front and rear waist regions and a crotch chassis attached to the elastic waist panel to define respective portions of the front and rear waist regions and the crotch region, wherein the crotch chassis includes a liquid-impervious sheet having a main region and opposite lateral portions lying outboard of the main region in the transverse direction and provided with leg elastic elements extending in the longitudinal direction, the opposite lateral portions respectively have
fold lines extending in the longitudinal direction,outer side zones lying outboard of the respective fold lines in the transverse direction andinner side zones lying inboard of the respective fold lines in the transverse direction, the outer side zones of the respective lateral portions are folded back inward and fixed to the associated inner side zones via associated bond zones extending in the longitudinal direction to form a pair of elastic lateral portions having folded back regions, respectively, the leg elastic elements include first leg elastic elements extending in the longitudinal direction and second leg elastic elements curving convexly inward, and outer side edges of the respective folded back regions are shaped so as to curve concavely outward along the second leg elastic elements. |
