くなる欠点があった。In this configuration, a sealing metal 9 is provided at one end opening of the simple insulating body 12.
and the output conductor 11 is connected to the opening at the other end of the insulating cylinder 12. However, the insulating cylinder 2 is designed to prevent discharge between the sealing metal 9 and the output conductor 11. This requires a sufficient height, which has the disadvantage that the amount of protrusion of the output conductor 11 from the anode body 1 becomes large.
