The photocatalytic apatite composition and its production method are disclosed. The photocatalytic apatite comprises a photocatalytic apatite having incorporated into the apatite crystal structure thereof a metal oxide having a photocatalytic action, such as titanium oxide, and a metal ion having an antimicrobial property, such as a silver ion or a copper ion. The photocatalyst apatite composition is capable of maintaining excellent decomposition and adsorption properties for various organic materials such as VOCs or specific adsorbing substances such as a virus for a long time and, at the same time, expressing an excellent antimicrobial property in a dark place as well as under daylight.
