<p>To provide a filament lamp and light irradiation type heat treatment device that eliminates device-by-device variation of the irradiation-intensity distribution on the article to be treated, a filament lamp (1) has multiple filament assemblies (41 to 45) with coiled filaments (411 to 451) connected to leads (412a to 452a, 412b to 452b) that supply electrical power to the filaments arranged within a tubular bulb (3), which is formed with hermetic seal areas (2a, 2b), extending along the bulb axis of the bulb, with power being supplied to each filament independently by electrical connection of the leads of the filament assemblies to multiple conductive parts (81a to 85a, 81b to 85b) located in the seal areas, and in which the leads (412a to 452a, 412b to 452b) of the filament assemblies (41 to 45) are inserted through the inside of the filaments (411 to 451).</p> |
