PROBLEM TO BE SOLVED: To provide a photocatalytic deodorizer capable of maintaining deodorizing performance for a long period of time by effectively exciting a photocatalyst on the whole surface of a photocatalyst sheet by a surface light source, and attaining miniaturization and a long service life.SOLUTION: The photocatalytic deodorizer 1 includes the photocatalyst sheets 61 and 62 arranged on the way of a ventilation passage in a ventilating manner with photocatalyst particles 61B and 62B mechanically supported between glass fibers 6A, and a surface light source substrate 5 arranged to intercept a ventilating direction on the upstream side in the ventilating direction from the photocatalyst sheets, mounted with a suitable number of LED chips 3 on the surface side facing the photocatalyst sheets, and formed with a suitable number of ventilation holes 4 in the substrate surface between the respective LED chips. The photocatalytic deodorizer 1 is configured such that air flowing in from the ventilation holes uniformly passes through the whole surfaces of the photocatalyst sheets.COPYRIGHT: (C)2012,JPO&INPIT【課題】面光源によって光触媒シートの全面で効果的に光触媒を励起させて脱臭性能を長期間維持でき、コンパクト化と長寿命化が図れる光触媒脱臭装置を提供する。【解決手段】本発明は、通風路の途中に配置される、光触媒粒子61B,62Bがガラス繊維6A間に機械的に担持された通気可能な光触媒シート61,62と、光触媒シートの通気方向の上流側にて通気方向を遮るように配置され、かつ、光触媒シートに対向する面側に適数個のLEDチップ3が実装されると共に各LEDチップ間の基板面に適数個の通風孔4が形成された面光源基板5とを備え、通風孔から流入する空気が光触媒シートの全面を均等に通過するようにした光触媒脱臭装置1である。【選択図】 図2
