Has an inner diameter of 3.4 mm, and has an inner wall surface of the exhaust pipe 5 and a thin tube 6.
Is about 0.33 mm. on the other hand,
The inner diameter of the thin tube 6 is 1.75 mm. Therefore, the alloy particles 8 having a diameter of 1.5 mm surely enter the thin tube 6 from the opening of the thin tube 6 and reach the inner bottom of the thin tube 6. Residual heat during molding of the glass tube 4 remains in the second stem 2b, and this heat causes the alloy particles 8 to melt and adhere to the inner bottom of the thin tube 6.

ともない。As described above, in the fluorescent lamp of the present invention, the gap between the inner wall surface of the exhaust pipe and the outer wall surface of the narrow pipe is smaller than the minimum diameter of the alloy. By fixing the alloy particles to the second stem so as to reduce the size, the alloy particles can be prevented from entering the glass tube. Therefore, it is possible to prevent the phosphor film from peeling due to the alloy particles rolling freely in the glass tube,
In addition, it can prevent the generation of contact noise with the glass tube,
Furthermore, the alloy grains do not become black shadows and are not visible from the outside.
