The present disclosure provides an absorbent article that has an excellent ability to diffuse bodily fluid, an excellent rate of absorption, and an excellent ability to prevent the fluid from returning even after repeatedly absorbing bodily fluid. This absorbent article is provided with an absorbent core (9) comprising superabsorbent polymer particles. The absorbent core (9) comprises a first layer (6) on the non-skin facing side and a second layer (8) on the skin facing side. The first layer (6) is provided with: groove parts (18) including a main groove part (19) that extends along the longitudinal direction L and passes therethrough in the thickness direction T; and base parts (20) extending along the longitudinal direction L. The main groove parts (19) and the base parts (20) alternately extend in the lateral direction W. The second layer (8) is provided with main groove part corresponding parts (22) and base part corresponding parts (24) at positions overlapping the main groove parts (19) and the base parts (20) in the thickness direction T. The superabsorbent polymer particles (32) in the base parts (20) and the main groove corresponding parts (22) have a smaller average density than the superabsorbent polymer particles (32) in the base part corresponding parts (24).
