The reflecting plate has reflection characteristics, in which light not travelling in a required direction among the lights irradiated from the cold-cathode can be guided to a required direction or position. When the current is energized on the reflecting plate, the reflecting plate generates heat and the heat generated at the reflecting plate is transmitted to the cold-cathode tube by radiation and transmission via air to heat it. Further, the reflecting plate is so installed as to surround at least a part of the cold-cathode tube, and so that the light irradiated from the cold-cathode tube may reach it directly without a light-shielding matter.
