Solder is filled into the space between each electrode and the sealed tube, and formed on the surface of the exterior surface of the electrodes. A method for forming the lamp electrode includes forming a cylindrically shaped electrode on an end of a sealed tube; maintaining a supply of solder in the liquid state; and dipping the end of the tube on which the electrode is formed into the solder.
