Provided is an absorbent article that comprises a post-processing tape member that has improved operability and handleability. An absorbent article (10) that has: a front-rear direction (L)； a width direction (W) that is orthogonal to the front-rear direction (L)； a back surface sheet (22) that is oriented away from the skin of a wearer； an adhesive part (70) that is provided on a non-skin-surface side of the back sheet (22)； and a post-processing tape member (60) that is fixed to the non-skin-surface side of the back sheet (22). The portion of the tape member (60) that contacts the back sheet (22) has a not-fixed part (64) that is not fixed to the back sheet (60). The not-fixed part (64) of the tape member (60) extends from the inside of the tape member (60) to at least one part of an outer edge (60e) of the tape member (60).提供針對操作性及使用性等的觀點予以改善的具備後處理用的膠帶構件的吸收性物品。吸收性物品(10)，具有：前後方向(L)；寬度方向(W)，是正交於前後方向(L)；背面薄片(22)，是朝與穿著者的肌膚相反側；黏著部(70)，是設置在背面薄片(22)的非肌膚面側；以及後處理用的膠帶構件(60)，是固定於背面薄片(22)的非肌膚面側。膠帶構件(60)接觸於背面薄片(22)的部分具有未固定於背面薄片(60)的非固定部(64)。膠帶構件(60)的非固定部(64)是從膠帶構件(60)的內側到達膠帶構件(60)的外緣(60e)的至少局部。
