It is preferably not more than 3 mm, and more preferably not less than 3 mm and not more than 9 mm. If the distance is less than 3 mm, the gap between the lamp surface and the catalyst surface is small, the flow rate of flowing air is insufficient, and the decomposition performance deteriorates. Further, the highest decomposition performance is obtained in the vicinity of 9 mm, and the decomposition performance deteriorates when it exceeds 15 mm. It is considered that this is because the rate at which the decomposition target passes through the photocatalyst without being sufficiently contacted with the photocatalyst increases.
