An object of the present invention is to adsorb non-degradable organic compounds such as PCB contained therein without damaging the soil, and to easily oxidize and decompose the adsorbed contaminants by a photocatalytic reaction using natural energy such as sunlight. It can be made harmless, has excellent strength, can withstand long-time use, has breakage resistance and durability, and by being given a suitable size and shape, it will not be destroyed even after recovery Provide a novel pollutant purifying agent that can be reused as it is. A contaminant purifying agent containing wood ceramics and a photocatalyst as main components, and preferably having a photocatalyst fixed to wood ceramics. A contaminant purifying agent exhibiting an effective purifying function for a hardly decomposable organic compound containing contaminants in soil, particularly an organic chlorine compound, especially PCB.
