Summary:The purpose of the present invention is to provide: a regenerated denitration catalyst having restored denitration performance compared to a denitration catalyst before use, by using a used denitration catalyst; and a production method therefor. In a regenerated denitration catalyst according to the present disclosure, a denitration catalyst, which contains a first titanium oxide as a main component and is used in a denitration reaction in which a nitrogen oxide in gas is decomposed into nitrogen and water using a reducing agent, coexists with a second titanium oxide having a specific surface area per unit weight larger than that of the first titanium oxide. The content of the second titanium oxide is preferably 10-90 wt% with respect to the total weight of the first titanium oxide and the second titanium oxide.
