To provide an air cleaning device capable of cleaning air while reducing pressure loss of a filter.SOLUTION: An air cleaning device includes: a photocatalyst filter supporting a photocatalyst, which extends from upstream to downstream of an air flow and has an upstream end and a downstream end; an ultraviolet light source that emits ultraviolet light toward the photocatalyst filter; a housing having walls capable of guiding air from upstream to downstream and accommodating the photocatalyst filter, which has a gap that allows air to flow between the photocatalyst filter and the walls facing the photocatalyst filter; and a connection holding mechanism that connects the upstream end to the walls of the housing and prevents air from flowing into the gap from upstream of the upstream end.SELECTED DRAWING: Figure 8 【課題】 フィルタの圧力損失を小さくしつつ、空気を清浄化できる空気清浄装置を提供する。【解決手段】 光触媒を担持させた光触媒フィルタであって、気流の上流から下流に向かって延在し、上流側端部と下流側端部とを有する光触媒フィルタと、光触媒フィルタに向かって紫外光を発する紫外光光源と、空気を上流から下流に向かって案内可能な壁部を有し、光触媒フィルタが収納される筐体であって、光触媒フィルタと向かい合う壁部と光触媒フィルタとの間に空気が流動可能な間隙部を有する筐体と、上流側端部を筐体の壁部に接続し、上流側端部よりも上流から間隙部への空気の流入を防止する接続保持機構と、を備える。【選択図】 図８
