To provide an electrode member group and its manufacturing method capable of preventing gas from leaking from a sealed part of a glass tube of a cold cathode fluorescent lamp, and a manufacturing method of the cold cathode fluorescent lamp using the electrode member group.
An electrode member 10 is provided with an electrode part 11, a lead part 12, and a glass part 13. An oxide film 12s is formed on a part covered by the glass part 13 on a front surface of the lead part 12. The electrode member group is provided with an electrode member A with a thick oxide film, and an electrode member B with a thin oxide film. The electrode member A is arranged on a side where the glass is heated with an inside of the tube containing atmosphere in fixing the electrode member A on the glass tube of the cold cathode fluorescent lamp. The electrode member B is arranged on a side where the glass is heated with the inside of the tube being vacuum. A plurality of the electrode members with oxide films of different thicknesses are prepared, and these electrode members are used selectively in fixing on the glass tube to prevent the gas in the tube from leaking from the sealed part of the glass tube.
