PROBLEM TO BE SOLVED: To provide a filament lamp capable of minimizing non-light-emitting areas between adjacent filaments while arranging an internal lead capable of carrying out independent power supply to each filament. SOLUTION: The filament lamp is characterized in that the internal lead 13d disposed between adjacent filaments 12a, 12b has a positioning part 17a extending in an axial direction of an arc tube 2 on a tip 15a, and a bride part 16a formed continuously with the positioning part 17a and bent in a radial direction of the arc tube 2, a sub coil 18a comprising tungsten is wound on the positioning part 17a, and the filament 12a is connected to the positioning part 17a wound with the sub coil 18a.
