PROBLEM TO BE SOLVED: To provide a method of manufacturing a cylindrical current fuse which enhances connection reliability of a fusible wire to a metal cap, by preventing the winding disturbance of the fusible wire.SOLUTION: In a method of manufacturing a cylindrical current fuse of such a structure that a fusible wire 12 is stretched through a through hole in a ceramic cylindrical body 11, temporary metals 13 are previously provided on the fusible wire 12 before and after a cut point C thereof at predetermined intervals, and then the fusible wire itself is cut at the cut point C. Preferably, the temporary metal 13 is a conductor for internal connection, such as solder or a crazing filler metal. A ceramic eyelet 21 is inserted into a formed ceramic cylindrical body 20, a metal cap 22 is fitted to the opposite ends of the cylindrical body and heated by heating means. The solder eyelets and temporary metal are thereby melted and integrated thus forming an internal electrode assembly 24. |
