To provide a method for producing a functional titania-clay composite with both an excellent substance adsorptive function and a visible light response type photocatalyst function at low temperature of the heat resistant temperature of clay or below.
This method for producing a functional titania-clay composite by imparting a visible light response type photocatalyst function to a clay compound that has an excellent substance adsorptive function includes adding the clay compound in a titania precursor sol solution, prepared with an ethylene glycol monomethyl ether as a solvent, after ultraviolet rays are irradiated thereto, and subjecting the mixture to heating and pressurizing processing as it is using a liquid as a heating medium within a temperature region including the heat resistant temperature of the clay and below.
