PROBLEM TO BE SOLVED: To provide a method capable of surely manufacturing a high-pressure discharge lamp with a high pressure-resistance. SOLUTION: A glass pipe 80 for a discharging lamp having a light-emitting tube part 1' to be turned into a light-emitting tube of the high-pressure discharge lamp and side tube parts 2' is prepared, and afterwards, a glass member 70 made of a second glass having a softening point lower than that of a first glass constituting the side tube parts 2' is inserted into the side tube parts 2', and a getter 75 is arranged on the side tube part 2'. Afterwards, a sealing part is formed by reducing the pressure inside the glass pipe 80, and adhering the side tube parts 2' to the glass member 70 by heating the side tube parts 2'.
