The lighting apparatus including a cathode tube, a photoconductive member to which light from the cathode tube is conducted through an edge surface thereof, and reflecting means for reflecting the light from the cathode tube toward the edge surface of the photoconductive member. The reflecting means has on the inner surface thereof reflecting mirrors which are made of silver and arranged at uniform intervals. With this structure, even when the reflecting means and the cathode tube are disposed close to each other, it is possible to prevent a leakage current from flowing from the cathode tube to the reflecting mirrors because the reflecting surfaces are separated from each other. This stops the leakage current from lowering a driving current of the cathode tube, and it is therefore possible to maintain high light emitting efficiency in the cathode tube. Moreover, since silver is used for the reflecting surfaces, reflecting efficiency of the reflecting means is maintained. The lighting apparatus can thus have a reduced thickness, more compact size, and improved surface brightness.
