Disclosed is a cleaning agent that exhibits an excellent cleaning effect due to the effects of a photocatalyst, an apatite complex, and cyclodextrin, and that can reduce the effect of the photocatalyst by absorption of moisture and prevent powder consolidation by silicon dioxide. The cleaning agent is a powder containing a photocatalyst and apatite and silicon dioxide, or composite particles of photocatalyst and apatite and silicon dioxide, or composite particles of photocatalyst and silicon dioxide, and cyclodextrin particles.
