摘要：
A light source device includes: an arc tube having a light emitting portion that emits light; a sub-reflection mirror that covers a part of the periphery of the light emitting portion and reflects the light emitted from the light emitting portion; a main reflection mirror that reflects the light emitted from the light emitting portion and the light reflected by the sub-reflection mirror; and a base that is formed separately from the main reflection mirror and to which the main reflection mirror is secured, wherein an arc tube securing portion for positioning and securing the arc tube is formed in the base.
