Provided is a disposable wearable article capable of maintaining a state in which the buttocks are covered at a rear-waist-panel side of a crotch region. This nappy (10) includes: a front waist panel (14); a rear waist panel (15); an absorption panel (16) between the front and rear waist panels; and a pair of leakage-prevention cuffs (60) which extend in the vertical direction (Y) at a skin-facing surface side of the absorption panel (16). The leakage-prevention cuffs (60) are provided with: proximal sections (62); and distal sections (63) in which a plurality of strip-like cuff elastic bodies (64) are disposed. Side extension sections (61) which are provided with a plurality of strip-like leg elastic bodies (65), and which extend in the vertical direction (Y) are positioned outside the proximal sections (62) in the horizontal direction (X). The number of sheets forming the side extension sections (61) is greater than the number of sheets forming the leakage-prevention cuffs (60). The elongation scale factor of the leg elastic bodies (65) is smaller than that of the cuff elastic bodies (64). The spacing dimension (W7) between the leg elastic bodies (65) in the horizontal direction (X) is greater than the spacing dimension (W6) between the cuff elastic bodies (64) in the horizontal direction (X).L'invention fournit un article jetable à porter qui permet de préserver un état dans lequel une partie fessier est recouverte par un côté panneau taille arrière d'une zone entrejambe. Une couche (10) contient un panneau taille avant (14), un panneau taille arrière (15), un panneau absorbant (16) entre les panneaux taille avant et arrière, et une paire de revers antifuite (60) se prolongeant dans une direction verticale (Y) côté face opposée à la peau du panneau absorbant (16). Les revers antifuite (60) possèdent une partie juxtaposition (62), et une partie éloignement (63) dans laquelle est disposée une pluralité de rangées de corps élastiques de revers (64).
