Abstract: PROBLEM TO BE SOLVED: To provide a light source device and a discharge lamp which can improve lighting performance.SOLUTION: A light source device comprises: an aperture member 3; and a shield electrode 4 having a first chamber and a second chamber divided by a partition plate. A cathode 1 is disposed in the first chamber of the shield electrode 4. The first chamber and the second chamber are communicated with each other via a second opening H2 which is disposed in the partition plate, and is located on a discharge path between the cathode 1 and the aperture member 3. The second chamber has a third opening H3 at which the first opening H1 of the aperture member 3 is located, and a fourth opening H4 for light emission. One end of the partition plate of the shield electrode 4 is fixed to a support part 11 comprised of an insulator. A voltage trigger-type switch switches the potential of the shield electrode 4 to either ground potential or floating potential.
