Abstract: A resistor and a manufacturing method thereof are disclosed. Since a ceramic tube formed of a ceramic material is used and the ceramic tube is joined to sealing electrodes by use of brazing rings, joining strength and durability of the resistor are considerably improved. The resistor may be stably used at a high voltage due to excellent heat dissipation characteristics thereof.
