ABSTRACT:
An electrode assembly for an arc tube which is free from the difficulty that tearing of a foil occurs in pinch-sealing the arc tube. One end portion of an electrode bar is overlapped with a molybdenum foil, and the electrode bar is connected to the molybdenum foil by spot-welding the overlapped portions of the two members, except for the tip end part of the end portion of the electrode bar, whereby the molybdenum foil is prevented from being damaged by the rectangular corner of the end portion of the electrode bar.
