Abstract: An ammonia-producing catalyst includes a p-type semiconductor, an n-type semiconductor, and a metal fine particle having a function of adsorbing nitrogen. In the ammonia-producing catalyst including the metal fine particle, generation of ammonia is promoted, and the generated amount of ammonia is increased. An ammonia-producing catalyst includes a p-type semiconductor, an n-type semiconductor, and an ammonia-fixing compound for fixing ammonia. In the ammonia-producing catalyst including the ammonia-fixing compound, a fixed yield of ammonia is sufficiently increased.
