PROBLEM TO BE SOLVED: To provide a deodorization filter to a gas including an odorous component inferior in adsorptivity, even if the generation amount thereof is temporally varied, capable of removing the odorous component from the gas stably and efficiently at any time.SOLUTION: Provided is a deodorization filter 10 comprising: a planar gas permeable container 14 in which network plates 12, 13 formed with many small openings 11 having gas permeability and light permeability are formed are provided on the upstream side and the downstream side and an odor treatment means 17 stored into the planar gas permeable container 14 and provided with granular porous body 16 having a grain size larger than the size of the small openings 11 and having odor component adsorptivity, whose surface is carried with a photocatalyst 15 activated with either or both light of visible light and ultraviolet light, and the odor component in the gas flowing from the upstream side into the planar permeable container 14 is adsorbed with the granular porous body 16 and is further decomposed with the photocatalyst 15.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】吸着性に劣る臭気成分を含むガスに対して、その発生量が時間的に変動しても、ガス中から臭気成分を常時安定して効率的に除去することが可能な脱臭フィルターを提供する。【解決手段】脱臭フィルター10は、通気性及び通光性を有する多数の小開口11が形成された網状板12、13を、上流側及び下流側に有する平板状通気性容器14と、平板状通気性容器14内に収納され、小開口11のサイズより粒径が大きく、表面には可視光線及び紫外線のいずれか一方又は双方の光で活性化する光触媒15が担持された臭気成分吸着性を有する粒状多孔質体16とを備えた臭気処理手段17を有し、上流側から平板状通気性容器14内に流れ込むガス中の臭気成分を、粒状多孔質体16で吸着すると共に光触媒15で分解する。【選択図】図1
