To alleviate any irritation experienced by the wearers skin and/or to restrict body waste leakage in a wearing article, a sheet lying at least in a first waist region of a chassis is joined to the chassis in first and second joined regions extending in a transverse direction and opposed to each other in a longitudinal direction. Additionally or alternatively, the sheet is joined to the chassis and a liquid-absorbent structure in a pair of longitudinal joined regions respectively extending along the side edges of the liquid-absorbent structure and opposed to each other in the transverse direction. The sheet is elastic and the chassis is non-elastic, and vice versa.
