<p>Disclosed is a cold cathode lamp comprising a light-transmitting insulating tube (1), first and second internal electrodes (2, 3) arranged inside the insulating tube, first and second external electrodes (4, 5) arranged outside the insulting tube and respectively connected with the first and second internal electrodes, first and second insulating bodies (8, 9) respectively covering the first and second external electrodes, a first counter electrode (10) arranged opposite to the first external electrode via the first insulating body, a second counter electrode (11) arranged opposite to the second external electrode via the second insulating body, a first insulating layer (12) surrounding the outer periphery of the first counter electrode, and a second insulating layer (13) surrounding the outer periphery of the second counter electrode. A plurality of such cold cathode lamps can be lighted by being connected in parallel with a power supply. In addition, generation of corona discharge near the outer peripheries of the counter electrodes can be suppressed.</p> |
