An arrangement with a relatively high pressure tightness in a super-high pressure mercury lamp (1) which is operated with an extremely high mercury vapour pressure is achieved in accordance with the invention in a super-high pressure discharge lamp (1) of the short arc type having a light emitting part (2) in which a pair of electrodes (6,7) are disposed opposite each other and which is filled with at least 0.15 mg/mm 3 mercury; and side tube parts (3) which extend from each side of the light emitting part (2) and in each of which a respective one of the electrodes (6,7) is partially hermetically sealed and is connected to a metal foil (8), by the area of the respective metal foil (8) which is connected to the respective electrode (6,7) has a smaller width (8a) than the width (8b) in the remaining area of the metal foil (8), the area with the smaller width (8a) wrapping at least partially around the outside surface of the electrode (6,7). |
