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.
