PROBLEM TO BE SOLVED: To provide a photocatalytic cleaning device capable of improving deodorizing efficiency and sterilizing efficiency by sufficiently applying catalysis by a light-excited catalyst substance to fluid to be processed. SOLUTION: In a photocatalytic cleaning device, a ultraviolet ray radiating means 10 for radiating ultraviolet rays to respective photocatalyst filters 5 and 6 is provided in a flowing space 8 formed between the upstream side photocatalyst filter 5 and the downstream side photocatalyst filter 6, and fluid to be processed flowing from the upstream side photocatalyst filter 5 is allowed to flow out of the downstream side photocatalyst filter 6 through the flowing space 8. A flowing impeding means for impeding the flow of the fluid processed is provided. |
