Disclosed is a long-life photocatalyst deodorization device (1) which effectively excites photocatalysts over the entire surface of a photocatalyst sheet and is capable of maintaining deodorization performance over a long period. Substrates (5 and 7) upon which vent holes (4) have been provided are disposed in parallel, and upon at least one substrate (5) of the two substrates, LEDs (3) are mounted. Between the two substrates, photocatalyst sheets (6) constituted by woven glass fiber material (6A) carrying photocatalyst particles (6B) and a frame (6C) supporting the material are disposed. The photocatalyst sheets and the two substrates are fixed to a housing (8), whereupon emitting surfaces of the LED light sources for exciting the photocatalysts and the photocatalyst sheets are disposed in parallel. Air fed from the vent holes is caused to pass through the photocatalyst sheets. The photocatalyst sheets are constituted by bundling glass fibers and weaving the fibers in a crisscross manner so as to have a predetermined aperture ratio such that ventilation is possible under low wind speed. The photocatalyst particles are mechanically held in contact between the glass fibers of the photocatalyst sheets.本發明,是以光觸媒薄片之全面,有效果地激勵光觸媒並可以長期間維持脫臭性能之長壽命的光觸媒脫臭裝置(1),是將設有通風孔(4)的基板(5、7)平行地配置,於2片基板之中之至少1片基板(5)構裝LED(3),並在上述2片基板之間,配置由:受載有光觸媒粒子(6B)的玻璃纖維織物(6A)及用以支撐該織物之框架(6C)所構成的光觸媒薄片(6),並將光觸媒薄片與2片基板固定於筐體(8),且將用以激勵光觸媒之LED光源的發光面與光觸媒薄片平行地配置,製成由通風孔所送入的空氣能夠通過光觸媒薄片,光觸媒薄片,是由:將玻璃纖維集束,以具有在低風速下能夠通氣之預定的開口率之方式縱橫交織所構成,光觸媒粒子,是被機械性地接觸保持在光觸媒薄片的玻璃纖維之間,來作為其特徵。1...光觸媒脫臭裝置3...LED4...通風孔5...基板6...光觸媒薄片7...對向基板8...筐體IN...空氣導入側OUT...空氣導出側
