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. |
