Zusammenfassung:	PURPOSE:To shut a discharge path to the peripheral members of a high voltage impressed on a light emitting member and enhance the reliability by refraining from formation of an electroconductive high-reflective evaporated film in that position on a reflex board which mates with the non-emission part of the light emitting means, and thereby accomplishing an insulative structure. CONSTITUTION:An electroconductive high-reflective evaporated film is formed in that position E of a reflex board which mates with the non-emission part of a light emitting means 1, while the position F mating with the non-emission part of the means 1 is left free from formation of such a film, and thereby an insulative structure is accomplished. This enables insulating a loop formed by the lead 4a of a fuse 4 together with the cut face of a reflector or a loop of the lead 4a with a fluorescent lamp starting conductor, and undeliberate discharge between them is prevented when high voltage impression is made at the time of starting the discharge, and thereby the starting characteristics of the fluorescent lamp are stabiliazed. A lamp holder 6 is made from a high heat, resisting material and also any temp, fuse is omitted so that the structure of the device is simplified, and stresses are reduced, and thus the reliability of the means 1 can be enhanced.
