To facilitate entry of an excretion liquid into a side pocket with a simple structure using an unperforated sheet. The abovementioned problem is addressed by an absorbent article characterized in that: a side pocket 70 extending in the longitudinal direction LD is provided on the lateral side of an absorber 56； the side pocket 70 is surrounded by a side cover 71 which reaches the back side of the absorber 56 from above the lateral portion of a top sheet 30 via an upper portion, an outer side, and a lower portion of the side pocket 70； a portion of the side cover 71 located above the lateral portion of the top sheet 30 includes a non-joining section 72 which is not joined to the top sheet 30, and includes a joining section 73 which is located on both the front and back sides of the non-joining section 72； and a gap 74, at the non-joining section 72, between the side cover 71 and the top sheet 30 is open above the top sheet 30 and toward the side pocket 70.本發明所要解決的問題在於提供一種吸收性物品，其無需在片上穿孔，利用簡單的結構使排泄液容易流入側袋中。 上述問題藉由下述吸收性物品得到了解決，該吸收性物品的特徵在於：在吸收體56的側方設置有在前後方向LD上延伸的側袋70，側袋70是被側罩部71包圍而成的部分，該側罩部從頂片30的側部上方起經過側袋70的上方、外側以及下方並到達吸收體56的背面側，側罩部71中的位於頂片30的側部上方的部分，具有未接合於頂片30上之非接合部分72、及位於該非接合部分72的前後兩側之接合部分73，非接合部分72中的側罩部71與頂片30之間的間隙74開口於頂片30的上方和側袋70上。
