Abstract

A discharge tube includes a pair of electrode devices mounted within a discharge tube body in an opposed relation to each other, each of the pair of electrode devices including an arc discharge electrode and a glow discharge electrode. An electron-radiating substance vaporized and emitted in a scattered manner from the arc discharge electrode is captured by the glow dis-charge electrode. The arc discharge electrode is composed of a sintered body containing the electron-radiating substance therein.
