Beschreibung
Zusammenfassung:	This invention provides an excimer lamp which is not only capable of improving the processing efficiency of a photocatalyst by effectively utilizing an irradiated ultraviolet ray but also has a good starting performance even when a xenon gas is used as a discharging gas. The excimer lamp has least a part of the discharging space (3) formed in a cylindrical discharging tube (2) in which the discharging gas is filled hermetically, a central electrode (4A) disposed at a center side and a peripheral electrode (4B) disposed at an outer periphery side, the peripheral electrode (4B) being formed by a porous photocatalyst sheet (11) having a conductive mesh (14) on which an anatase type titanium oxide (16) to be used as a photocatalyst is carried, the conductive mesh (14) being formed into an undulating shape continuously extending in one direction, the porous photocatalyst sheet (11) being wrapped around the discharging tube (2) in such a manner that the undulations are brought into line-contact with the outer surfa
