PROBLEM TO BE SOLVED: To perform ventilation to the periphery of an ultraviolet lamp without leakage of ultraviolet rays. SOLUTION: In this air cleaner to incorporate an ultraviolet lamp 61 in a ventilation passage and have a sterilization function by ultraviolet rays of ventilation air, the ultraviolet lamp 61 is contained in a box body (an unit case 62) having a draft hole (a slit 62f). Further, a shield member (a louvered piece 62e) is provided to prevent leakage of radiation light from the ultraviolet ray lamp 61 to the outside of the box body through the ventilation hole (the slit 62f). |
