[Problem] To provide a purification unit and de-odorizing device capable of efficiently generating photocatalytic reactions with few light sources. [Solution] The purification unit (100) is provided with LEDs (21), a curved reflecting plate (30) that reflects light emitted from the LEDs (21) and irradiates same essentially perpendicularly onto a purification plate (10), and the purification plate (10) that undergoes photocatalytic reactions as a result of being irradiated with the light reflected by the reflecting plate (30). The photocatalytic film (13) of the purification plate (10) is configured so that thickness increases in the negative direction of the x-axis. The disposition of the LEDs (21) and the curved shape of the reflecting plate (30) are set so that the intensity of the light irradiated on the purification plate (10) is greater in the negative direction of the x-axis, thereby allowing the photocatalytic reaction to be accelerated on the surface of the purification plate (10) on the negative side of the x-axis compared to the positive side of the x-axis. It is also possible to generate photocatalytic reactions across a broad area of the purification plate (10).La présente invention vise à fournir une unité de purification et un dispositif désodorisant capables de générer efficacement des réactions photocatalytiques avec peu de sources de lumière. La présente invention concerne par conséquent lunité de purification (100) qui est dotée de DEL (21), dune plaque réfléchissante incurvée (30) qui réfléchit la lumière émise par les DEL (21) et irradie ladite lumière de manière sensiblement perpendiculaire sur une plaque de purification (10) et de la plaque de purification (10) qui subit des réactions photocatalytiques en résultat de son irradiation par la lumière réfléchie par la plaque de purification (30). Le film photocatalytique (13) de la plaque de purification (10) est configuré de manière à ce que lépaisseur augmente dans le sens négatif de laxe des ab
