PROBLEM TO BE SOLVED: To provide a nonwoven fabric that prevents fumaric acid from falling off therefrom, in the nonwoven fabric containing fumaric acid in a solid state.SOLUTION: A fumaric acid-containing nonwoven fabric is a fabric constituted of a resin fiber. The resin fiber contains a fumaric acid-containing fiber including a substrate resin and fumaric acid in a solid state. The fumaric acid in the solid state indwells in the substrate resin and at least a part of the fumaric acid in the solid state is exposed from a surface of the fiber.
