PROBLEM TO BE SOLVED: To provide an absorbent article with enhanced effects of lateral leakage suppression.SOLUTION: An absorbent article (1) has an absorbent body (10) provided with an absorbent core (40) and a pair of leakage prevention walls (20) which are provided on both side parts in a width direction of the absorbent body (10) and can rise on a skin side in a thickness direction. The leakage prevention walls (20) have skin side parts (23) and non-skin side parts (24) and are provided with bonding parts (27) where at least a part of surfaces of the skin side parts (23) and the non-skin side parts (24) that face each other are bonded. The bonding parts (27) are provided inside ends of the leakage prevention walls (20) in the width direction. The absorbent body (10) has a crotch stretchable part (15) which stretches at least in one direction of the longitudinal direction and the width direction in the center part of the width direction and the longitudinal direction. The bonding parts (27) and the crotch stretchable part (15) overlap at least in a part of each other in the longitudinal direction. The bonding parts (27) are arranged nearer outside in the width direction than the crotch stretchable part (15).SELECTED DRAWING: Figure 2【課題】横漏れ抑制の効果が向上した吸収性物品を提供することができる。【解決手段】吸収性コア（４０）を備えた吸収性本体（１０）と、吸収性本体（１０）の幅方向の両側部に設けられ厚さ方向の肌側に起立可能な一対の防漏壁（２０）とを有し、防漏壁（２０）は肌側部（２３）と非肌側部（２４）を有し、肌側部（２３）と非肌側部（２４）との互いに対向する対向面同士の少なくとも一部が接合された接合部（２７）を備え、接合部（２７）は幅方向において防漏壁（２０）の先端よりも内側に設けられており、吸収性本体（１０）は幅方向及び長手方向の中央部に、長手方向と幅方向の少なくとも一方向に伸縮するクロッチ伸縮部（１５）を有し、接合部（２７）及びクロッチ伸縮部（１５）は長手方向において少なくとも互いの一部が重複し、接合部（２７）はクロッチ伸縮部（１５）よりも幅方向の外側に配置されている吸収性物品（１）。【選択図】図２
