Provided is an absorbent article that can stabilize the position of the leak-proof cuff, alleviate the uncomfortable feeling given to the wearer, and suppress the leakage of excrement associated with the positional shift of the leak-proof cuff. The absorbent article (10) includes a longitudinal direction and a width direction perpendicular to each other, a front waistline region (S1), a back waistline region (S2), and a crotch region ( S3), a rear stretchable region (32) that is provided in the rear waistline region and can be stretched in the width direction, extends between the front waistline region and the rear waistline region, and is disposed on both sides across the center in the width direction. A pair of leak-proof cuffs (46). The standing fulcrum (46a) of the leak-proof cuff overlaps with the rear elastic region in the thickness direction in the rear waistline region. The distance between the pair of leak-proof cuffs in the crotch region extends from the widening start point (46c) in the leg retraction region (S31) to the rear waistline region. The distance between the pair of leak-proof cuffs in the rear waistline region is longer than the distance between the pair of leak-proof cuffs in the front waistline region.防漏カフの位置を安定させ、着用者に与える違和感を緩和し、防漏カフの位置ズレに伴う排泄物の漏れを抑制できる吸収性物品が提供される。吸収性物品（１０）は、互いに直交する長手方向及び幅方向と、前胴回り域（Ｓ１）、後胴回り域（Ｓ２）、及び前胴回り域及び後胴回り域との間に配置された股下域（Ｓ３）と、後胴回り域に設けられ、幅方向に伸縮可能な後側伸縮領域（３２）と、前胴回り域と後胴回り域との間を延び、幅方向における中心を挟んで両側に配置された一対の防漏カフ（４６）と、を有する。防漏カフの起立支点（４６ａ）は、後胴回り域において、後側伸縮領域と厚さ方向で重なっている。股下域における一対の防漏カフどうしの距離は、脚繰領域（Ｓ３１）内の拡幅開始点（４６ｃ）から後胴回り域にかけて広がっている。後胴回り域における一対の防漏カフどうしの距離は、前胴回り域における一対の防漏カフどうしの距離よりも長い。
