A wearing article which can be hygienically compactly folded by using constituent members of the diaper without requiring members of other means is provided. First side edges (11) and second side edges (12) extending in the longitudinal direction (Y) intersecting the lateral direction (X) are respectively formed in front and rear waist regions (8, 9). Support members (13, 14) are mounted to those portions of an inner surface sheet (6) which respectively correspond to the first side edges (11). First engaging regions are formed through the support members (13, 14), and hook elements (15, 16) for mechanical fasteners are mounted to a chassis (2) through the support members (13, 14). Second engaging regions are formed on those portions of the inner sheet (6) which correspond to the second side edges (12), and loop elements (17, 18) are mounted to those portions of the inner sheet (6) which correspond to the second side edges (12). Waist elastic members (21) extending in the lateral direction (X) are mounted in a stretched state in the front and rear waist regions (8, 9) such that the waist elastic members (21) can stretch and contract. The support members (13, 14) are constructed from a fabric sheet engageable with the hook elements (15, 16) and form third engaging regions.
