Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a light source device capable of reducing the amount of electromagnetic wave leaked from a light source device to the outside is more surely reduced to be equal to or less than a predetermined regulated value while securing the availability of light rays, and to provide a projection type display device with the light source device. SOLUTION: The light source device 1 is equipped with an electrodeless discharge lamp 2 performing discharge and light emission by application of a high frequency current, and various optical parts (lens arrays 21 and 22, a PS converter 8, a condenser lens 9, a mirror 61 or the like and a lens 63a or the like) guiding light to an optical modulation element such as liquid crystal light valves 63b, 65b and 71b are covered with a conductive case part 11. The case part 11 has a first aperture 11a on which light is made incident and a second aperture 11b which emits the light. COPYRIGHT: (C)2009,JPO&INPIT
