Claims

[Scope of utility model registration request]

A filament consisting of a tubular enclosure and a plurality of filament elements arranged in the tubular enclosure to extend along the tube axis of the tubular enclosure, adjacent filament elements connected by short-circuiting core wires. Each of the filament elements comprises a coiled light emitting part and a coiled connecting part continuous to both ends thereof, and the adjacent connecting parts of the adjacent filament elements have bent parts at both ends thereof. A tube-shaped light bulb, wherein both ends of a short-circuiting core wire having a short-circuiting core wire are inserted and connected, and the connecting portion of the filament element has a protruding portion extending outward from the outer diameter of the connecting portion at the tip thereof.
