PROBLEM TO BE SOLVED: To provide a toilet apparatus capable of maintaining hydrophilicity by a relatively short period of irradiation time.SOLUTION: A toilet apparatus includes a light source device that applies ultraviolet rays to a bowl part that is provided in a toilet bowl and in which a photocatalytic film is formed. The light source device applies the ultraviolet rays with an irradiation intensity of 30 microwatt/square centimeter or more to at least any part of the bowl part. |
