PROBLEM TO BE SOLVED: To provide a short arc type discharge lamp including an electrode having a structure where a heat transfer body can be sealed in an electrode by a relatively simple method and a manufacturing method by which the electrode can be manufactured easily, in a short arc type discharge lamp having a pair of electrodes at the inside of a light emitting tube and including a heat transfer body sealed in an enclosed space of at least one electrode and a manufacturing method of the short arc type discharge lamp.SOLUTION: An electrode 4 comprises a tubular container member 6 with a bottom and a lid member 7. An upper end face of a tubular side wall of the container member 6 and a lower end face of the lid member 7 are diffusively bonded together, an enclosed space 8 is formed by the container member 6 and the lid member 7 having been bonded, and a heat transfer body M is sealed in the enclosed space 8.SELECTED DRAWING: Figure 1 |
