Abstract
To maintain the relative positional relationship between an inner tube and an inner electrode of a dielectric barrier discharge tube having a roughly cylindrical, double tube arrangement of an outer tube coaxially arranged about an inner tube with a discharge space defined therebetween, an outer electrode on an outer surface of the outer tube, an inner electrode on an inner surface of the inner tube, and a discharge gas which forms excimer molecules by a dielectric barrier discharge filling said discharge space, despite repeated expansion and contraction of the inner electrode due to the dielectric barrier discharge lamp being repeatedly turned on and off, according to the invention, the inner electrode is formed of a substantially tubular metal component or the like, and a motion preventing component is provided at opposite ends of the inner electrode for maintaining an axial position of the inner electrode relative to the inner tube.
