Abstract
Light-transmittable linear photocatalytic filter material that can be arranged in parallel in the longitudinal direction without causing a filter to have the form of a barrel when the filter is made of a bundle of a number of such photocatalytic filter materials, each 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, wherein a maximum value of heights from said outer side surface to said 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 said outer side surface to said photocatalyst layer in regions of both ends thereof.
