The absorbent article (100) of the present invention has an elastic region (20) in which an elastic member (19) extending in the width direction (Y) is disposed at least at a central portion in the width direction (Y) of the back side portion (B). And between the elastic region (20) and the absorbent core (14a) in the longitudinal direction (X), there is an inelastic region (25) in which the elastic member (19) is not disposed. The front sheet (12) has a concave-convex region (F) at a portion overlapping the inelastic region (25). The uneven portion (F) convex portion (41) is formed in a specific pattern, and has a longitudinal groove portion (51) continuous between the plurality of convex portions (41) in the longitudinal direction (X), and a plurality of convex portions (41) A lateral groove portion (55) continuous in the width direction (Y). The longitudinal groove portion (51) is larger than the lateral groove portion (55).本發明之吸收性物品(100)於背側部(B)之寬度方向(Y)上之至少中央部，具有配置有沿該寬度方向(Y)延伸之彈性構件(19)之彈性區域(20)，且於長度方向(X)上之該彈性區域(20)與吸收性芯(14a)之間具有未配置彈性構件(19)之非彈性區域(25)。正面片材(12)係於與非彈性區域(25)重疊之部位具有凹凸區域(F)。凹凸區域(F)係凸部(41)以特定之圖案形成，且具有通過複數個凸部(41)間而於長度方向(X)連續之縱槽部(51)、及通過複數個凸部(41)間而於寬度方向(Y)連續之橫槽部(55)。縱槽部(51)蜿蜒之程度大於橫槽部(55)。
