This invention provides an absorbent article adapted to prevent loose waste material or the like from leaking out from the article. A diaper 10 includes a chassis 14, a liquid-absorbent structure 20 and containment cuffs 30. An inner sheet 40 in the chassis 14 includes a plurality of ridges and grooves extending in a longitudinal direction Y. Between a rear end 22 of the liquid-absorbent structure 20 and rear waist elastics 62, a spacing zone 80 is defined. Cuff elastics 36 are attached in a contractible manner to cuffs inner side edges 33 wherein opposite ends of the cuff elastics 36 are spaced from cuffs front and rear ends 31, 32, respectively. Between cuffs inner side edges 33 and the inner sheet 40, inner bond zones 81 extend to the spacing zone 80. Upon contraction of the cuff elastics 36, the cuffs inner side edges 33 are pulled inward in the longitudinal direction Y and folded about the inner ends 81a of the respective inner bond zones 81 toward the wearers body so as to form a fold. Formation of the fold makes a portion of the inner sheet closer to its rear end 42 than the fold to form a folded trough on the garment-facing side. This crest and trough cooperate with each other to define a pocket.
