Abstract
In a discharge tube manufacture line, electrode clamps are attached to both sides of an electrode lead except on a predetermined adhesion area to fix a glass bead. Then, a power section is driven to energize the area between the electrode clamps. The surface of the predetermined adhesion area is heated and oxidized. The glass bead is welded to the oxidized surface of the predetermined adhesion area.
