This absorbent article (1) is provided with an absorbent body (4) and a surface sheet (2) arranged on the skin-facing surface side of the absorbent body (4). The absorbent body (4) is configured by including an absorbent core (40) that exhibits liquid absorbency, and a core wrapping sheet (41) that covers the skin-facing surface of the absorbent core (40). The absorbent core (40) includes a water-absorbing fiber (12F) and fiber lumps (11) including fibers (11F) that exhibits a weak water-absorbency which is weaker than that of the water-absorbing fiber (12F). The ratio between the liquid diffusion surface area of the absorbent core (40) and the liquid diffusion surface area of the core wrapping sheet (41), namely, the former over the latter, is at least 0.7.本發明之吸收性物品(1)具備吸收體(4)、及配置於該吸收體(4)之肌膚對向面側之正面片材(2)。吸收體(4)係包含液體吸收性之吸收性芯體(40)、及被覆該吸收性芯體(40)之肌膚對向面之包芯片材(41)而構成。吸收性芯體(40)包含吸水性纖維(12F)、及含有吸水性低於該吸水性纖維(12F)之弱吸水性之纖維(11F)的纖維塊(11)。吸收性芯體(40)之液體擴散面積與包芯片材(41)之液體擴散面積之比率以前者/後者計為0.7以上。
