PROBLEM TO BE SOLVED: To provide an absorbent article which has absorbency in an excretion part-facing part and flexibility in a rear part, can stably absorb without the breaking by being twisted when being worn, and can reliably prevent leakage in the back.SOLUTION: An absorbent article 1 is provided with an absorbent core 4 shaped to be long in a front-back direction of the absorbent article and has an excretion part-facing part B arranged to face a liquid excretion part of a wearer and a rear part C that is arranged in the back with respect to the excretion part-facing part. The absorbent core 4 has a front projecting region 41 in a central part in a width direction of the excretion part-facing part B and a rear projecting region 42 in a central part in a width direction of the rear part C. The front projecting region 41 and the rear projecting region 42 are respectively thicker than a thickness of a peripheral region 43 of the absorbent core and are respectively partitioned by groove parts 44, 47 extending in a width direction Y of the absorbent core to form a plurality of small absorbing parts 45, 48 aligned in a longitudinal direction X of the absorbent core 4. A length c of a small absorbing part 48 in the rear projecting region 42 is shorter than a length b of the small absorbing part 45 in the front projecting region 41.【課題】排泄部対向部における吸収性と後方部における柔軟性とを兼ね備え、装着時にヨレて壊れずに安定的に吸収可能であり、後ろ漏れを確実に防止することができる吸収性物品を提供すること。【解決手段】吸収性物品の前後方向に長い形状の吸収性コア4を備え、着用者の液排泄部に対向配置される排泄部対向部B及びそれより後方に配される後方部Cを有する吸収性物品1であり、吸収性コア4は、排泄部対向部Bの幅方向中央部に前方中高領域41、後方部Cの幅方向中央部に後方中高領域42を有し、前方中高領域41及び後方中高領域42は、それぞれ、吸収性コアの周辺領域43における厚みよりも厚みが厚く、それぞれ、吸収性コアの幅方向Yに延びる溝部44によって分割され、吸収性コア4の長手方向Xに沿って並んだ複数の小吸収部45,47が形成されており、後方中高領域42の小吸収部48の長さcが、前方中高領域41の小吸収部45の長さbより短い。【選択図】図2
