Is provided. When the toilet seat 3 is turned down, the magnet 22 faces the reed switch 21, and the LED 8 can be energized by a signal from the reed switch 21.

  In the Western-style toilet 1 configured as described above, when the LED 8 is turned on, light is irradiated into the toilet bowl 1a. When this light is UV (ultraviolet light), antifouling action by UV is exhibited. When the light is visible light, an antifouling action is achieved by holding the photocatalyst on the inner surface of the toilet bowl 1a. Even when the LED 8 is a UVLED, an excellent antifouling effect can be obtained by providing a photocatalyst on the inner surface of the toilet bowl 1a. Note that a photocatalyst may also be provided in other parts such as the upper surface of the rim.
