<P>PROBLEM TO BE SOLVED: To provide a light source device and a projector capable of appropriately cooling a light emitting tube. <P>SOLUTION: A light source device 5 comprises: a light emitting tube 51 having a light emitting part 511 and a first sealed part 512; a first reflecting mirror 52 having a substantially curved reflection surface 5221; and an accommodating body 6 accommodating them. The accommodating body 6 has a duct part 7 located above the light emitting tube 51, extending along the center axis of a luminous flux reflected by the reflection surface 5221, and configured such that cooled air circulates toward the opposite direction to the travelling direction of light reflected by the reflection surface 5221. The duct part 7 includes: a first opening part 6134 located closer to the leading end side in the traveling direction than the open end of the first reflecting mirror 52; a wall part 6135 forming the basal end side edge of the first opening 6134 in the travelling direction and serving as the final end of the duct part 7; and an inclining part 6132 configured such that cooled air is inclined toward a surface opposite a surface on which the first opening 6134 is formed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
