< Topic >Purification unit and the deodorization device which can make the photocalytic reaction cause efficiently with the little illuminant are offered.SolutionsAs for purification unit 100, reflecting the light which radiation is done from LED21, and LED21 in purification board 10 abbreviation vertically incidence the purification board 10 which causes the photocalytic reaction due to the fact that the light which is reflected by reflector 30 of the curved surface form which it can point and reflector 30 is irradiated and, it has. Photocatalyst membrane 13 of purification board 10 is formed in order for thickness to become large, in X axial negative direction. Curved surface form of the arrangement and reflector 30 of LED21 is set in order for strength of the light which is irradiated to purification board 10 to be inclined on X axial negative direction side. Because of this, as for the surface of X axial negative direction side of purification board 10, the photocalytic reaction can be promoted in comparison with the surface of X axial forward side of purification board 10. In addition, extending to the range whose purification board 10 is wide, the photocalytic reaction can occur.< Selective figure >Figure 6【課題】少ない光源によって光触媒反応を効率良く生じさせることができる浄化ユニットおよび脱臭装置を提供する。【解決手段】浄化ユニット100は、LED21と、LED21から出射された光を反射して浄化板10に略垂直に入射させる曲面形状の反射板30と、反射板30によって反射された光が照射されることにより光触媒反応を起こす浄化板10と、を備えている。浄化板10の光触媒膜13は、X軸負方向において厚みが大きくなるよう構成されている。LED21の配置と反射板30の曲面形状は、浄化板10に照射される光の強度がX軸負方向側に偏るよう設定される。これにより、浄化板10のX軸負方向側の面は、浄化板10のX軸正方向側の面に比べて、光触媒反応が促進され得る。また、浄化板10の広い範囲に亘って光触媒反応が生じ得る。【選択図】図6
