Abstract: Absorbent article suppressing occurrence of malodor after use while preventing a rash on a wearer's skin. The absorbent article includes an absorbent body, and a fumaric acid-supported sheet disposed on a skin surface side of the absorbent body. The fumaric acid-supported sheet is a sheet which supports fumaric acid particles having an average particle diameter of 30 ?m or less, and/or a sheet in which at least a part of constituent fibers is coated with fumaric acid. When being in contact with the body fluid or the like, fumaric acid is not immediately but slowly dissolved so that alkalization at the area around fumaric acid can be prevented over a long period of time. In addition, fumaric acid has an action of inhibiting proliferation of putrefactive bacteria and, therefore, can prevent occurrence of malodor from the absorbent article having absorbed the body fluid or the like.
