Abstract

PURPOSE:To suppress the increase in the starting voltage of an electrode for an electric-discharge lamp, and improve the life performance of the electrode by using an electron discharging matter consisting of scandium oxide, and less than given proportion of metal thorium. CONSTITUTION:An electrode for an electric-discharge lamp consists of an electrode core 10 made of a heat-proof metal such as tungsten, an inner coil 11 and an outer coil 12 that are wound around the core 10, and an electron emitting matter 13 which coats the coils 11 and 12 and is fixed by high temperture heating. The electron emitting matter 13 consists of more than 10wt% of scandium oxide, and less than 90wt% of metal thorium.
