PROBLEM TO BE SOLVED: To provide an ammonia-producing catalyst capable of sufficiently improving a fixing yield of ammonia.SOLUTION: An ammonia-producing catalyst 1 includes a p-type semiconductor 11, an n-type semiconductor 12 and an ammonia-fixing compound 13 for fixing ammonia. The ammonia-fixing compound 13 preferably is a compound containing at least one or more ions selected from F, Cl, Br, I, OH, COO, HBO, HCO, ClO, NO, HSOand HPO(x: an arbitrary value of 1 to 5, y: an arbitrary value of 0 to 3, n: an arbitrary value of 1 to 4). |
