Further, in the device described in JP-A-64-90035, the cloth supporting the photocatalyst is wound closely together in a state where the cloths are in contact with each other in a multi-spiral sleeve shape. Some photocatalysts are blocked by a sleeve in the foreground, making it difficult for ultraviolet rays to reach, and thus there is a problem that the entire photocatalyst is not used effectively. Also, JP-A-3-1571
No. 25 has a problem that the photocatalyst carrier has a flat plate shape, so that the photocatalyst loading is low and the contact area with the processing fluid is small, so that the decomposition efficiency is low.
