There is provided a cold cathode fluorescent lamp including a transparent tube including first and second light-emitting areas defined by partitioning an inner space of the transparent tube, a first terminal electrode positioned in the first light-emitting area and at a longitudinal end of the first light-emitting area located closer to an end of the tube, a second terminal electrode positioned in the second light-emitting area and at a longitudinal end of the second light-emitting area located closer to the other end of the tube, a first intermediate electrode positioned in the first light-emitting area and at the other longitudinal end of the first light-emitting area, a second intermediate electrode positioned in the second light-emitting area and at the other longitudinal end of the second light-emitting area, a first lead-in wire connected to the first terminal electrode through the longitudinal end of the first light-emitting area, a second lead-in wire connected to the second terminal electrode through the longitudinal end of the second light-emitting area, a third lead-in wire connected to the first intermediate electrode through the other longitudinal end of the first light-emitting area, and a fourth lead-in wire connected to the second intermediate electrode through the other longitudinal end of the second light-emitting area. The above-mentioned cold cathode fluorescent lamp makes it possible to lower a break-down voltage and a discharge voltage down to about halves of them in a conventional fluorescent lamp, and hence, discharged electrons are not attracted to a metal part. Thus, it is possible to prevent a cold cathode fluorescent lamp from not turning on due to electron discharge.
