PROBLEM TO BE SOLVED: To provide an absorbent article hardly leaving rubber marks around the waist of a wearer.SOLUTION: An absorbent article comprises an absorbent body (10) having an absorbent core (11A), and a pair of waist parts (20), and the waist part (20) comprises a skin side sheet part (221) arranged at a side closest to the skin, and a plurality of rubber threads (23) expandable in a transverse direction. In the waist part (20), flexural rigidity of the skin side sheet part (221) by a KES method is 0.0096 N m2/m×10-4 or less, there is provided an inner layer sheet part (21) between the skin side sheet part (221) in the thickness direction of the waist part (20) and the rubber threads (23) and on a waist side of the absorbent body (10) in a vertical direction, and flexural rigidity of the inner layer sheet part (21) by the KES method is higher than flexural rigidity of the skin side sheet part (221).SELECTED DRAWING: Figure 5COPYRIGHT: (C)2020,JPO&INPIT【課題】着用者の胴回りにゴム痕を付きにくくする吸収性物品を提供すること。【解決手段】吸収性コア（１１Ａ）を備える吸収性本体（１０）、及び、一対の胴回り部（２０）を有し、胴回り部（２０）は、最も肌側に配置された肌側シート部（２２１）、及び、横方向に伸縮可能な複数の糸ゴム（２３）を備える吸収性物品であって、胴回り部（２０）では、肌側シート部（２２１）のＫＥＳ法による曲げ剛性は０．００９６Ｎ・ｍ2／ｍ×１０-4以下であり、胴回り部（２０）の厚さ方向における肌側シート部（２２１）と糸ゴム（２３）との間であり、縦方向における吸収性本体（１０）より胴回り側において、内層シート部（２１）を有し、内層シート部（２１）のＫＥＳ法による曲げ剛性は、肌側シート部（２２１）の曲げ剛性より高いこと。【選択図】図５
