ABSTRACT:
A light emitting device capable of achieving a small exit area, high directivity, and low loss; a manufacturing method thereof; an illumination device using this light emitting device; and a projector are provided. The light emitting devices16include an LED (light emitting element)25, in the form of a rectangular light emitting element, having a light emitting part23for emitting illumination light; a substrate26for fixing the LED25; a spacer27having a mirror surface27A for reflecting the illumination light emitted from the LED25; and a tapered rod (columnar light guide unit)28having a device-side incident surface (incident surface)28A upon which illumination light is incident, tapered-rod side surfaces28B serving as total reflection surfaces for totally reflecting illumination light received from the device-side incident surface28A, and the device-side exit surface (exit surface)28C which has a larger area than the device-side incident surface28A and which emits the illumination light totally reflected at the tapered-rod side surfaces28B.
