The invention provides a short arc discharge lamp, which is provided with a hollow container sealing a hydrogen getter absorbing hydrogen and penetrating hydrogen in a luminous tube, the hollow container is not fixed at the luminous tube and electrodes. In the short arc discharge lamp, in the luminous tube (11), a pair of electrodes (13, 14) formed by a main body part (13A, 14A) and a shaft part (13B, 14B) disposed continuously with the main shaft are oppositely disposed, a hydrogen getter formed by sealing getter materials absorbing hydrogen in the hollow container penetrating hydrogen is disposed, the short arc discharge lamp is characterized in that: the shaft part (13B) is provided with a housing (15) holding the hydrogen getter. |
