る反射鏡を設けたことを特徴とする光源装置。[Claims for Utility Model Registration] Light incident from one end surface of a transparent rod is diffused and reflected by a light diffusing section provided along the longitudinal direction on the circumferential surface of the rod, and the other end surface of the rod is diffused and reflected. In the light source device, the light is reflected by a light reflecting part provided on one end face of the rod, and then emitted from the rod in its circumferential direction to irradiate the target. a reflecting surface for reversing light other than light directed toward the irradiated object out of the light emitted from the circumferential surface near the end of the rod toward a central portion in the longitudinal direction of the rod and re-entering the rod; A light source device comprising: a reflecting mirror having a slit through which the light emitted from the rod passes toward an object to be irradiated.
