Abstract: There is provided a deodorizing material having particularly high deodorization capabilities for ammonia, acetaldehyde, and toluene. The deodorizing material of the present invention comprises fibrous activated carbon; and (A) an aromatic amine and a sulfate of the aromatic amine or (B) an aromatic amine, a sulfate of the aromatic amine, and sulfuric acid, supported on the fibrous activated carbon, wherein a total substance amount of the aromatic amine and the sulfate of the aromatic amine supported per gram of the fibrous activated carbon is 0.85 to 1.35 mmol, and a ratio of the total substance amount (mmol) of the aromatic amine and the sulfate of the aromatic amine supported per gram of the fibrous activated carbon relative to a total substance amount (mmol) of the sulfate of the aromatic amine and the sulfuric acid supported per gram of the fibrous activated carbon ([total substance amount of the aromatic amine and the sulfate of the aromatic amine]÷[total substance amount of the sulfate of the aromatic amine and the sulfuric acid]) is 5.0 to 7.5.
