PURPOSE: To prevent any generation of re-operation of a glow starter when it is used for lighting of a fluorescent lamp by fixing a specified amount of a metal barium to the inner wall of an airtight case, an electrode structure or the like.

CONSTITUTION: An electrode structure 6, which is installed in the airtight case 1 of a glass bulb, is constituted by providing a stem 5 with both an electrode 2 fixed to one inner lead-in wire and a movable bimetal electrode 4 one end of which is fixed to another inner lead-in wire 3. At least 1mg of a metal barium such as BaNb is fixed to each of the fixed and the movable electrodes 2 and 4 of the electrode structure. In addition, the case 1 is charged with argon gas used as a discharge-facilitating gas. As a result, the re-operation voltage can be heightened, and the generation of re-operation can be prevented.
