The present invention provides a photocatalyst particle comprising titanium dioxide particles, a zeolite particle, and a carbon layer. The titanium dioxide particles are adsorbed on a part of an external surface of the zeolite particle. The carbon layer coats a part of an external surface of the zeolite particle other than the part of the external surface of the zeolite particle on which the titanium dioxide particles are adsorbed. The carbon layer is in contact with a part of surfaces of the titanium dioxide particles. At least a part of the other part of the surfaces of the titanium dioxide particles is not coated with the carbon layer and are exposed on a surface of the photocatalyst particle. The present invention provides a photocatalyst particle used even in an alkaline aqueous solution.
