Claims

[Scope of utility model registration request]

A back-type enclosure, a filament coil arranged to extend along the tube axis of the back-type enclosure, an inner end of the filament coil inserted into the end coil, and an outer end of the filament coil arranged to extend along the tube axis of the back-type enclosure. A lead wire having an outer diameter smaller than the inner diameter of the end coil of the filament coil, which is sealed in the sealing part of the mold sealing body, and a radially outer diameter of the filament coil formed at the tip of the inner end of the lead wire. a support part that is provided through a bending part that is bent in the opposite direction, and that supports the lead wire by coming into contact with the inner wall of the back-shaped enclosure; and a part of the lead wire that is located within the end coil of the filament coil. 1. A tube-type light bulb comprising a connecting member provided on the outer periphery for connecting the portion and the end coil.
