PROBLEM TO BE SOLVED: To provide an air cleaning device for a clean room capable of introducing a part of illumination light from the outside into a ventilation flue in which a visible light responsive catalyst is disposed. SOLUTION: In this air cleaning device for the clean room, a dust removing filter 20 is disposed at a downstream side of a case body 6 for air distribution, a transparent daylighting section 14 for introducing the illumination light b from the external, is formed on a case body part at an upstream side with respect to the dust removing filter, and the visible light responsive catalyst 22 is disposed on a proper part in the case body communicated with the daylighting section. The visible light responsive catalyst is activated by utilizing the illumination light introduced from the daylighting section to decompose contaminant in the air. COPYRIGHT: (C)2011,JPO&INPIT
