A method for manufacturing a cold cathode ray tube is provided to adjust a distance between a positioning device and a heating coil according to a predetermined distance, so that the cathode ray tube has a predetermined length. A cold cathode ray tube having a movable end(11) and a stationary end(12) is prepared, in which an electrode(13) protrudes from each of the movable and stationary ends. The movable end of the cold cathode ray tube penetrates a clip(21), a heating coil set(22), and a guide member(23) which are provided on a bent tube processing machine(20), and is positioned on a standby position of the machine. Then, the cold cathode ray tube is moved towards the guide member by using a positioning device(24) installed on one side of the clip.
