Abstract:
A light-transmittable linear photocatalytic filter material comprising a light-transmittable linear material, a number of particulate materials bonded to an outer side surface of the light-transmittable linear material and a photocatalyst layer formed on said outer side surface and said number of particulate materials,said light-transmittable linear photocatalytic filter material being for the production of a light-transmittable linear photocatalytic filter in which light enters one end or both ends of said light-transmittable linear material, propagates inside said light-transmittable linear material and leaks into said photocatalyst layer and said photocatalyst layer is irradiated with the leaked light, characterized in that: a maximum value of heights from the outer side surface of the linear material to the surface of the photocatalyst layer in a central region of said light-transmittable linear material in the longitudinal direction is smaller than a maximum value of heights from the outer side surface of the linear material to the surface of the photocatalyst layer in regions of both ends thereof.
