The present invention is intended to provide an absorbent article that is excellent in anti-odor effect at the time of disposal. A pants-type disposable diaper includes an anti-odor tape (70) that has a first gas barrier layer (71) coupled to the pants-type disposable diaper and a second gas barrier layer (72) that is stuck in a separable manner to either front or back surface of the first gas barrier layer (71) via an adhesive agent (73) containing an anti-odor agent. The anti-odor tape (70) takes an anti-odor measure by separating the second gas barrier layer (72) from the first gas barrier layer (71) to expose the adhesive agent (73) to the outside at the time of disposal of the pants-type disposable diaper.
