ABSTRACT:
An electric discharge lamp has a ceramic luminous tube5and filled with xenon gas, a pair of electrodes9, 10held by the ceramic luminous tube, and a glass outer tube6accommodating the ceramic luminous tube and the pair of electrodes. The ceramic luminous tube includes a luminous portion7emitting light by electric discharge, and a pair of small diameter tube portions8, 8respectively connected to both end portions of the luminous portion in a longitudinal direction. Value of P/(r•t) is not less than 4.8 and not more than 32, where P (atm) is pressure of xenon gas filled into the ceramic luminous tube, r (mm) is an inner diameter of the luminous portion of the ceramic luminous tube, and t (mm) is thickness of the luminous portion of the ceramic luminous tube.
