In order to solve the problem of providing an absorbent article that can prevent the formation of three-dimensional gathers from being inhibited due to the seepage of an adhesive from a top sheet, overlapping sections (21a, 21b), which overlap both a leakage prevention section (50a, 50b) and an absorbent body (4) in the thickness direction (Z) of the absorbent article (1), are formed on the top sheet, and non-joined regions (22a, 22b), which are not joined to the absorbent body (4) by the adhesive (H), are formed on the absorbent body-side surfaces of the overlapping parts (21a, 21b).
