ABSTRACT:
A method for manufacturing a high-pressure discharge lamp of the double-ended type having excellent resistance to high-pressure and wherein the internal diameter of a portion of the high-pressure discharge lamp where a light-emitting section and a side tube are adjacent can be reduced without restricting the maximum diameter of an electrode on a side where it projects into the light-emitting section. An electrode assembly 105 is arranged within an evacuated glass bulb 2 such that an end of electrode 102 where a coil 102b is wound is positioned within the light-emitting section 3. In this condition, the portion where the light-emitting section 3 and the side tube 4a (4b) are adjacent is heated by a burner 300. The internal diameter of the side tube 4a (4b) can thereby be formed with a reduced-diameter section 7, whose diameter is smaller than that of the electrode rod 102a without restricting the diameter at the location of the coil 102b.
