Abstract
Starting performance is improved by efficient UV-light irradiation, suppressing creeping discharge or atmospheric discharge at the outside of a glow discharge tube, and preventing cracks in a pinch seal portion even when an external force is exerted in the direction of bending a lead. In a discharge tube for emitting a UV-light, a light emitting chamber is formed on one side of a pinch seal portion for sealing an electrode assembly, and a lead protrusion port is formed on the opposite side thereof while pinching the seal portion, the lead protrusion port is formed as a sleeve having a predetermined gap relative to the lead, an external electrode disposed to the outside of the light emitting chamber includes a hold formed by bending fabrication of a metal plate.
