(57) [Summary] [PROBLEMS] To prevent the occurrence of a shadowed portion unlike the case where a separate light source is used, to improve the utilization rate of the catalyst, to increase the catalyst activity, and to use extra light. The decomposition reaction can be promoted without the need for an intense light source or a large light source area, Accordingly, a photocatalytic reaction device and a photocatalytic reaction method capable of improving power efficiency and further reducing power consumption are provided. The photocatalyst includes a photocatalyst, a photocatalyst carrier for supporting the photocatalyst, and a light source for irradiating the photocatalyst with light. Body The light source is disposed between the high-voltage terminals 2 connected to the power supply 3, and discharge light generated at the photocatalyst-carrying member by the supply of current to the high-voltage terminals 2 is used as a light source. |
