The present invention makes it possible to increase the air permeability of a region in the vicinity of leg openings of an absorbent article while maintaining the effect of preventing leakage of liquid. This absorbent article is provided with: leg openings (35) disposed on both widthwise-direction W sides, the leg openings (35) being disposed around the legs of a wearer when worn； and a leakage-preventing sheet (60a) provided on the non-skin side from an absorbent body (40), the leakage-preventing sheet (60a) extending further outward in the widthwise direction W than does the absorbent body (40). At least the leg openings (35) are provided with moisture-permeable sheets (64), (70) having higher moisture permeability than does the leakage-preventing sheet (60a), the moisture-permeable sheets (64), (70) being provided on the skin side of the leakage-preventing sheet (60a). The moisture-permeable sheets (64), (70) have a junction part joined to the leakage-preventing sheet (60a), and an inside gather (74) that can rise from the leakage-preventing sheet (60a), the inside gather (74) not being joined to the leakage-preventing sheet. The inside gather (74) extends outward in the widthwise direction W from a rise base point (B1). The inside gather (74) has a first elastic member (75) that expands and contracts in a longitudinal direction (L).本發明，是邊維持防止液體的洩漏的效果，邊可提高吸收性物品的腿圍開口部附近的區域的通氣性。吸收性物品具備：腿圍開口部(35)，其是被配置在寬邊方向(W)的兩側，在穿用狀態被配置在穿用者的腿圍、以及防漏薄片(60a)，其是比吸收體(40)更被設在非肌膚面側，並比吸收體(40)更朝寬邊方向(W)的外側延伸。至少在腿圍開口部(35)，在防漏薄片(60a)的肌膚面側設有比防漏薄片(60a)更具有高的透濕度的透濕薄片(64)、(70)。透濕薄片(64)、(70)具有：被接合在防漏薄片(60a)的接合部、以及沒有被接合在前述防漏薄片，可從防漏薄片(60a)立起的內側褶邊(74)。內側褶邊(74)，是從立起基點(B1)朝寬邊方向(W)的外側延伸。內側褶邊(74)具有在前後方向(L)伸縮的第1彈性構件(75)。
