To provide an absorbent article rapidly diffusing body fluid in an absorber, and reducing anxiety about leakage.SOLUTION: An absorbent article comprises a roughly slender body which has a liquid-permeable top sheet, a liquid non-permeable rear surface sheet, and an absorber provided between the top sheet and the rear surface sheet. The absorber has a rear surface side absorber layer arranged at the rear surface sheet side, and a top side absorber layer provided at the top sheet side. The rear surface side absorber layer has a pair of belt-like high-density parts extending in a roughly longitudinal direction, and a width between the belt-like high-density parts is 10-30 mm in a crotch corresponding area corresponding to the crotch of a wearer at the time of wearing.SELECTED DRAWING: Figure 1【課題】吸収体において体液を速やかに拡散させ、且つ漏れに対する不安感を軽減した吸収性物品を提供する。【解決手段】透液性の表面シートと、不透液性の裏面シートと、前記表面シートと前記裏面シートとの間に設けられた吸収体とを有する略細長形状の本体を備えた吸収性物品であって、前記吸収体は、前記裏面シート側に配置された裏面側吸収体層と前記表面シート側に配置された表面側吸収体層とを有し、前記裏面側吸収体層は、略長手方向に延びる一対の帯状高密度部を有し、前記一対の帯状高密度部間の幅は、装着時に装着者の股間に対応する股間対応領域において、１０～３０ｍｍである。【選択図】図１
