    摘要： Provided herein is a light-emitting apparatus which is capable of causing the light emitted at the entire face of a fluorescent material to be exteriorly emitted with no interference and with enhanced light emission efficiency, thereby attaining an exteriorly radiated high brightness light. A cathode electrode 10 is mounted on a periphery of a transmission member 30, the anode electrode 15 is also mounted on a domain opposite to a light transmission member 30, and the surface 16a of the fluorescent material 16 to be mounted on a top layer of the anode electrode 15 is formed with a concave face. In accordance therewith, even when the cathode electrode 10 is offset mounted on a periphery of the light transmission member 30 it can be caused to precisely face the surface 16a of the fluorescent material 16 and the excitation light from the entire face of the surface 16a of the fluorescent material 16 can made incident onto the light transmission member 30 without interference from the cathode electrode 10 or the like.
