Provided is an excimer lamp that is not only capable of effectively using irradiated ultraviolet rays and enhancing the processing efficiency of a photocatalyst, but that also has favorable lighting properties even when xenon gas is used as the discharge gas. At least a portion of a discharge space (3), formed in a discharge tube (2) in which a discharge gas is hermetically sealed, is formed as a cylindrical space, a central electrode (4A) on the center side of the discharge space and a peripheral electrode (4B) on the external peripheral side of the discharge space are provided, and the peripheral electrode (4B) is provided by winding a porous photocatalyst sheet (11) in which anatase-type titanium oxide (16) as a photocatalyst is supported on a conductive mesh (14) having wave-shaped undulations formed therein that are continuous in one direction, so that the undulations are in line contact with the external surface of the discharge tube (2). |
