Zusammenfassung:	PURPOSE: To prevent the generation of light unevenness in the light-emitting surface of a light conduction board and to miniaturize the device by integratedly forming the bottom surface part reflector and the side surface part reflector of a reflector. CONSTITUTION: The bottom surface part reflector 4a and the side surface part reflector 4b of a reflector 4 are integratedly formed. Broken line-form punching work 4c is performed in the boundary between the reflectors 4a, 4b of adjacent two surfaces. Thereby, the bending position is definitely determined. The window-form punching work 4d of the form in which square holes continue in the boundary between the remaining reflectors 4a, 4b is performed. In the work 4d, the height H of the window is determined by taking into consideration the dimensional tolerance and the like at the time of manufacturing the light conduction board 2.
