PROBLEM TO BE SOLVED: To provide a fluorescence lamp, which has long life-time and safety, without breaking of an end part glass even in the last stage of the electrode life-time in the fluorescence lamp, which is lit with high frequency of lighting, combined with an electronic stabilizer. SOLUTION: It has valve 2, in which a fluorescent substance 1 has been applied to its inside, lead wires 4a and 4b supported with the end part glass 5 of the valve 2, and an electrode coil 3 bridged by the lead wires 4a and 4b. Lead wires 4a and 4b are surrounded with mineral tubules 6a and 6b, and the one end of the mineral tubules 6a and 6b are laid under the valve end part glass 5.
