Abstract:
The present invention addresses the problem of increasing the absorbent capacity, liquid diffusibility, and collecting capacity of an absorbent article having a multilayered absorber. This absorbent article is provided with a liquid-permeable top sheet (10) located on the skin-facing-surface side, a liquid-impermeable back sheet (20) located on the non-skin-facing-surface side, and a plurality of absorbers stacked in the direction of thickness between the top sheet (10) and the back sheet (20). The plurality of absorbers includes at least an upper-layer absorber (30) located on the top-sheet (10) side and a lower-layer absorber (40) located on the back-sheet (20) side. The upper-layer absorber (30) has an upper opening (31) having a prescribed length and width, the upper opening (31) extending in the longitudinal direction, and the lower-layer absorber (40) has a lower opening (41) having a shorter length and width than the upper opening (31), the lower opening (41) extending in the longitudinal direction. The upper opening (31) and lower opening (41) at least partially overlap in the direction of thickness.
