PURPOSE:To supply a large current thereby to obtain a pair or more of electrodes which are not easily separated and resistant to heat by composing the electrodes provided on the outer surface of a pipe of a dielectric of a plating layer and a conductor formed on the layer. CONSTITUTION:An AC discharge tube has a pipe (e.g., a ceramic tube or a quartz tube) of a dielectric, plating layers 2, 2' formed directly on the outer surface of the pipe as the inner layers of the electrodes formed on the outer surface of the pipe, and conductors 3, 3' of the outer layers of the electrodes. The conductors 3, 3' are formed of wirings, and so wound on the layers 2, 2' as to provide predetermined strength. Then, the wound wirings 3, 3' are soldered 4, 4' to the layers 2, 2'. Thus, even if the layers 2, 2' are thin, a large current can flow, and even when a force is applied to the current terminal connected to the wirings 3, 3', they are not easily separated and are resistant to heat. |
