The subject of the present invention is to provide a gas processing device that uses a structure in which the power supply line is not exposed to ozone generated by ultraviolet rays radiated from a discharge lamp to suppress the deterioration of the power supply line.The gas processing device of the solution is provided with a first end including a first opening area constituting an intake port, arranged at a position spaced apart from the first end in a first direction, and having a first end constituting an exhaust port The second end of the two opening regions, and the hollow part connecting the first opening region and the second opening region is formed in the frame of the inner main body, and has a tube arranged in the hollow part and having a shape extending in the first direction The body, the first electrode, and the second electrode use a discharge lamp that radiates ultraviolet rays from the tube body by applying a voltage between the first electrode and the second electrode, and a power supply part arranged on the outside of the frame body to pass more than the body part. The wiring on the first end portion side electrically connects the power supply portion and the first and second power supply lines of the first electrode and the second electrode, respectively.本發明的課題，係提供利用設為供電線不會暴露於因為從放電燈放射的紫外線所產生之臭氧中的構造，抑制供電線之劣化的促進的氣體處理裝置。解決手段的氣體處理裝置，係具備包含具有構成吸氣口之第一開口區域的第一端部、配置於對於第一端部隔開於第一方向的位置，並且具有構成排氣口之第二開口區域的第二端部、及連絡第一開口區域與第二開口區域的中空部形成於內側的本體部的框體、具有配置於中空部內，並且呈現延伸於第一方向之形狀的管體、第一電極、第二電極，利用對第一電極與第二電極之間施加電壓，從管體放射紫外線的放電燈、配置於框體的外側的電源部、以通過比本體部更靠第一端部側之方式配線，分別電性連接電源部與第一電極、第二電極的第一供電線及第二供電線。
