PROBLEM TO BE SOLVED: To enhance the commodity value of a cold cathode discharge tube by deterring occurrence of sputtering in the processing stage for stabilizing the cold cathode discharge tube to the utmost and, as a result, by avoiding the black spot and a blackening phenomenon on the inner surface of a discharge tube before the shipping of commodity as much as possible and by lengthening the life of the discharge tube. SOLUTION: This stabilization circuit of the cold cathode discharge tube is constituted so that the capacitor of 2.2μF is connected in parallel with the distance tube connected to the power source of 260 to 330 V and the discharge tube is made to be operated under the condition of 20 Hz.
