摘要

The present invention is a niobium nitride having a composition represented by the composition formula Nb3N5, wherein the valence state of the structural element Nb is substantially +5. This method for producing the niobium nitride comprises a nitriding step whereby an organic niobium compound and a nitrogen compound gas are reacted and the organic niobium compound is converted to a nitride.
