(57) [PROBLEMS] To provide a photocatalyst device which is compact, has a high degree of freedom of installation place, and can efficiently irradiate a photocatalyst with ultraviolet rays. A bulk carrier 1 made of fibers, a photocatalyst 2 supported on the bulk carrier 1, and a light emitting diode 3 for irradiating the bulk carrier 1 with ultraviolet light having a wavelength of 360 to 400 nm are provided. Is characterized by. Since the bulk carrier 1 made of fibers has a high degree of freedom of shape, it can be arranged even in a narrow and complicated portion, and the photocatalyst can be efficiently irradiated with ultraviolet rays by reflection / diffusion in the fibers. |
