摘要： A surge absorber and a manufacturing method thereof are disclosed. Since a ceramic material with excellent mechanical strength is used to form a ceramic tube and the ceramic tube is joined to sealing electrodes by use of brazing rings according to the method of manufacturing the surge absorber, durability of the surge absorber is considerably improved. Since the ceramic tube is completely sealed, the surge absorber may be stably used at a high voltage.
