Abstract
A ultraviolet irradiation apparatus includes: a first electrode block and a second electrode block located apart from each other in a first direction or located in an electrically-insulated state in the first direction; a recessed groove formed on a side surface of each of both the blocks; a first discharge lamp partially fitted into the recessed grooves formed in both the blocks and located across the both blocks; a power supply part for supplying electrical power to the first discharge lamp; a first current-carrying member electrically connecting the first electrode block and the power supply part; a second current-carrying member capable of electrically connecting the second electrode block and the power supply part at an electrical potential different from that of the first current-carrying member; and a light irradiation window for extracting ultraviolet light emitted from the first discharge lamp to outside.
