Abstract
A fuse and a manufacturing method thereof are disclosed. Since a nonconductive member formed of a ceramic material with excellent mechanical strength and a ceramic tube are used and the ceramic tube is joined to sealing electrodes by use of brazing rings, durability of the fuse is considerably improved. The fuse may be stably used at a high voltage by improving time-lag characteristics.
