To provide an air cleaner capable of enhancing maintainability, reducing influence of ultraviolet rays on the inside and outside of equipment, and further reducing noise.SOLUTION: An air cleaner 1 includes a casing 10 that forms a flow passage between a suction port 19 and an outflow port 15, a fan 2 installed in the casing 10 for blowing air from the suction port 19 toward the outflow port 15, a first filter 4 installed upstream of the fan 2 along the cross section of the flow passage in the casing 10, an ultraviolet ray lamp 5 installed upstream of the first filter 4 in the casing 10, a lamp housing part 30 which is installed in the casing 10 and surrounds the ultraviolet ray lamp 5 at the upstream side and the lateral side crossing the normal of the cross section of the flow passage and of which the downstream side is open, and a first shield plate 6 opposite to the suction port 19 installed between the lamp housing part 30 and the suction port 19. A second shield plate 7 and a fan introduction part 40 for making the air flow rate uniform are installed upstream of the fan 2.SELECTED DRAWING: Figure 1 【課題】メンテナンス性を向上し、紫外線による機器内部・外部への影響を低減し、更に騒音を低減することができる空気清浄機を提供する。【解決手段】空気清浄機１は、吸込口１９と送風口１５との間に流路を形成するケーシング１０と、ケーシング１０内に設けられて、吸込口１９から送風口１５に向かって空気を送風するファン２と、ケーシング１０内で、ファン２よりも上流側で流路の流路断面に沿って設けられた第１フィルタ４と、ケーシング１０内で、第１フィルタ４よりも上流側に設けられた紫外線ランプ５と、ケーシング１０内に設けられて、紫外線ランプ５を上流側及び流路断面の法線に交差する側方から囲うとともに、下流側が開口したランプ収容部３０と、ランプ収容部３０と吸込口１９との間で、吸込口１９に対向する第１遮蔽板６と、を備える。ファン２の上流側には、第２遮蔽板７と空気の流速を均一化するファン導入部４０とが設けられている。【選択図】図１
