Abstract

PURPOSE: To prevent the cracks and the metal foil breakage during the lighting and eliminate the leak, by establishing a particular relation between the thickness and the width of the seal portion to keep the maximum strain below a predetermined limit.
CONSTITUTION: Metal foil conductors 5, 5 made of molybdenum etc., which are connected to main electrodes 2, 2 and an auxiliary electrode 3, are sealed in the seal portions 4, 4, and each metal foil conductors 5, 5 and 6 are connected to the external leads 7, 7 and 8. The seal portions are formed in such a manner that the thickness 2t and the width W of the seal portion satisfy the relation 6.5≤W/2t≤ 9.0.
