摘要

A high-voltage discharge lamp has a bulb made of quartz glass, a pair of electrodes and molybdenum foils, wherein the pair of electrodes are arranged so as to oppose each other and are joined to respective ones of the molybdenum foils, and the bulb and molybdenum foils are hermetically sealed at seal portions of the bulb. The joints between the pair of electrodes and the respective molybdenum foils are covered by cylindrical members having slits on an outer surface and/or an inner surface thereof.
