ABSTRACT:
A light emitting device, which includes at least one light emitting element, has a light emission portion which emits diffused light, at least one optical element upon which a concave portion is formed in which the diffused light which has been emitted from the light emitting element is incident, and which converts the diffused light into approximately parallel light and emits the approximately parallel light thereof to the exterior, and a holder portion which has one side surface, another side surface, and at least one through hole which extends between the one and the other side surfaces, and which holds the light emitting element and the optical element, in which the optical element is inserted into the through hole from a side of the one side surface of the holder portion, and is fixed therein, and the light emitting element is inserted into the through hole to which the optical element is fixed from a side of the other side surface of the holder portion, and is fixed therein.
