Abstract: In a fluorescent indicator tube wherein a cathode filament is provided in an envelope at a prescribed space from anode segments arranged on a substrate, one end of said cathode filament is fixed to a plate-shaped cathode filament-fixing rigid terminal fitted to one end of the substrate, and the other end of said cathode filament is attached to a plate-shaped cathode filament-fixing resilient terminal secured to the other end of the substrate. The plate-shaped filament-fixing resilient terminal comprises a plate member capable of being resiliently deformed in the direction in which the cathode filament is stretched and a frame securely supporting said plate member and fitting the whole of the resilient filament-fixing terminal to the substrate. The forward section of the deformable plate member is made broader than the rear section. The resiliently deformable plate member is bent outward, that is, in a direction in which the cathode filament is stretched, in order to prevent the cathode filament from touching the free end of the deformable plate member. A cutout line extending lengthwise of the deformable plate member is provided in the broader section. That portion of this broader section which projects from the rear section is bent upward along the cutout line. When one end of the cathode filament is placed between the bent portion and flat portion of the forward section of the deformable plate member, then the bent portion is folded up and welded to the flat portion securely to put therebetween and clamp the cathode filament.
