PROBLEM TO BE SOLVED: To provide a short arc type extra-high pressure mercury lamp capable of lighting brightly at initial stage after starting, a lighting source device using the short arc type extra-high pressure mercury lamp, and to provide a projection image display device capable of sufficiently increasing luminance at the initial stage after starting.;SOLUTION: In the short arc type extra-high pressure mercury lamp 10, two electrodes 21 are arranged opposed to each other in a space 12, in which mercury, a halogen substance, and a rare gas are filled. As the rare gas, Xe is filled into the space 12 with a pressure of 40 kPa-1520 kPa (0.4-15 atm) at 300 K.;COPYRIGHT: (C)2008,JPO&INPIT
