Abstract

PURPOSE:To facilitate insertion of heat/light emitting substance of a filament and preventing inner electroconductive member from inclination at the time of crushed sealing of the ends or the heat/light emitting substance from bending at its end by furnishing a straight tube portion at an open end of a circular glass bulb. CONSTITUTION:A straight portion 1a with length l is provided at either or both of the open ends of a circular glass bulb 1 with a certain space between the two ends. This straight portion 1a facilitates insertion of the heat/light emitting substance of filament 5, into the bulb 1. This also prevents the electroconductive member of molybdenum foil 6 inside the bulb from inclination and the ends of the heat/light emitting substance of filament 5 from bending at the time of forming a crushed sealing part 2 at the end.
