To prevent backflow and reduce the risk of highly absorbent polymer particles leaking from a connecting section of a wrapping sheet. An absorbent article characterized in that: an absorbent body (56) is obtained by mixing and accumulating fibers and highly absorbent polymer particles (56P)； a wrapping sheet (58) comprises an intermediate part positioned on the front side of the absorbent body (56) and two side parts that are folded around to the rear side of the absorbent body (56) from the intermediate part； the leading ends of the two side parts of the wrapping sheet (58) overlap at the rear side of the absorbent body (56) and form a connecting section (58c)； the weight of the highly absorbent polymer particles is greater than the weight of the fibers in the absorbent body (56)； and the content of the highly absorbent polymer particles (56P) in the absorbent body (56) increases in either a stepwise manner or a continuous manner from the rear side toward the front side.本發明所欲解決的問題在於防止回滲，並且減少自包裝片的連接部洩漏高吸收性聚合物粒子的可能性。 為了解決上述問題，本發明提供一種吸收性物品，其特徵在於：吸收體56是由纖維和高吸收性聚合物粒子56P混合集聚而成，包裝片58具有位於吸收體56的正面側之中間部分、及自此中間部分朝吸收體56的背面側折回之兩側部分，並且包裝片58的兩側部分的前端部於吸收體56的背面側重疊而形成連接部58c，其中，吸收體56的高吸收性聚合物粒子的重量比纖維的重量更大，並且，吸收體56的高吸收性聚合物粒子56P的含有率，是隨著自背面側向正面側而階段性地或連續性地變高。
