A narrow central opening (5) and a pair of narrow lateral openings (6, 6) extending in a longitudinal direction (X) are formed in a base-layer absorbent core (231). A top-layer absorbent core (230) and the central opening (5) are superposed in plan view, and the central opening (5) extends the entire length in the longitudinal direction (X) of the top-layer absorbent core (230). An opening extending in the longitudinal direction (X) and penetrating through the top-layer absorbent core (230) in the thickness direction thereof is not formed in the region where the base-layer absorbent core (231) and the central opening (5) are superposed in plan view. A pair of standing gathers (24, 24) is provided on skin-facing surfaces of left- and right-side sections of an absorbent core (23). Standing-gather-forming elastic members (26) and the absorbent core (23) are superposed in plan view in the unfolded and extended state of the absorbent article (1).
