A disposable wearing article adapted to prevent body exudates from leaking sideways beyond leg-opening peripheries and to prevent the wearer's body from being soiled with body exudates.Front and rear waist regions (13, 14) are elastically contractible at least in a transverse direction (X) and a crotch region (15) is provided in laterals with a pair of lateral elastic regions (40) which are elastically contractible in a longitudinal direction (Y). A liquid-absorbent structure is located between the pair of lateral elastic regions. A cantilever bending resistance in a nearly central portion of the crotch region (15) including a liquid-absorbent structure (35) is in a range of about 15 to about 140 mm and a length dimension (L2) measured from an inner side edge (40a) of one of the lateral elastic regions (40) to an inner side edge (40a) of the other lateral elastic region (40) is in a range of about 0.5 to 1.0 times of a length dimension (L1) in the transverse direction (X) of a waist-opening periphery (21a) in any one of the front and rear waist regions (13, 14) measured under tension of the front and rear waist regions (13, 14) in the transverse direction (X).
