PROBLEM TO BE SOLVED: To obtain a photocatalyst-containing fiber-treating agent having antimicrobial properties, deodorant properties and flexibility by allowing photocatalytic fine particles to be carried between layers of a smectite. SOLUTION: This photocatalyst-containing fiber-treating agent is obtained by mixing a suspension containing a smectite such as a limitless layer-expansive clayey mineral having crystalline three-layer structure, e.g. montmorillonite, and having 0.1-15μm average particle diameter, and a cationic organic compound such as lauryltrimethylammonium chloride, with photocatalytic fine particles comprising a combination of one or more kinds selected from titanium oxide, zinc oxide and tungsten oxide, and having 0.001-0.3μm, preferably 0.003-0.2 primary particle diameters to allow the photocatalytic fine particles to be carried between layers of the smectite.
