PROBLEM TO BE SOLVED: To provide a manufacturing method of a high-pressure lamp for easily improving lamp performance in accordance with miniaturization. SOLUTION: After inserting electrode (filament) mounts (5), (6) and (10) into a sealing vessel (1) in a working vessel (G) set in a non-oxidizing atmosphere as shown in figure, both opening ends (2b), (3b) of the sealing vessel (1) are fused and closed, and next, a prescribed buried portions (5s), (6s) are buried into a first and a second sealing positions (2a), (3a), respectively. Therefore, impurities etc. are blocked from the sealing vessel (1) etc. during an assembly, and small-sized high-pressure lamps (A) or (B) (not shown) excellent in lamp performance can be produced in a well-arranged manner and with ease.
