Abstract
A light emitting device of the present invention includes: a laser diode group which generates a plurality of laser beams; a cylindrical light emitting element which emits incoherent light in response to the plurality of laser beams; and a light guide irradiation section which (i) guides the plurality of laser beams entered via a light incidence plane toward a light irradiation plane and (ii) irradiates the light irradiation area of the cylindrical light emitting element with the plurality of laser beams thus guided. The light irradiation plane of the light guide irradiation section has an area which is smaller than that of the light incidence plane.
