PROBLEM TO BE SOLVED: To provide a photocatalytic deodorizing device capable of being applied to a wider range by forming vent holes in a glass fiber fabric constituting a photocatalyst sheet.SOLUTION: Two photocatalytic sheets 3 are disposed parallel between two LED mounting substrates 5 which are disposed parallel, in which a plurality of LED chips 13 are mounted on surfaces opposite to each other, and in which a plurality of vent holes 5a are formed. The two photocatalytic sheets 3 are respectively composed of: a first glass fiber fabric 21 which carries photocatalytic fine particles and in which vent hole 31 are formed and a second glass fiber fabric 23 which is provided closely in contact with both surfaces of the first glass fiber fabric 21, in which vent holes 31 are formed, but which has no photocatalytic fine particles.COPYRIGHT: (C)2013,JPO&INPIT【課題】 光触媒シートを構成するガラス繊維織物に通気孔を形成して、圧力損失を低減し、より広い範囲への適用を可能とした光触媒脱臭装置を提供する。【解決手段】 互いに対向する面に複数のLEDチップ13が搭載されて平行に配設されるとともに複数の通風孔5aが形成されている2枚のLED実装基板5の間に2枚の光触媒シート3を平行に配設し、この2枚の光触媒シート3をそれぞれ光触媒微粒子を坦持するとともに通気孔31の形成された第1のガラス繊維織物21と、この第1のガラス繊維織物21の両方の面に密接して設けられ、通気孔31の形成された光触媒微粒子のない第2のガラス繊維織物23とで構成する。【選択図】 図2
