ABSTRACT:
A light source includes an arc tube which emits light, a reflector which reflects the light emitted from the arc tube, and a holding unit which holds the reflector. The holding unit has an air supply port through which cooling air is introduced into the light source on the light emitting side of the arc tube, and a first rectifying portion which guides cooling air having been supplied from the air supply port and passed through the light emitting side of the arc tube toward an area above the arc tube.
