Summary:PROBLEM TO BE SOLVED: To improve a property of a parting operation of a thermal fuse by decreasing an oxide content as coming closer to a side welded to a lead conductor end of a thermal fuse element as compared to the center, and by varying a distribution of content density even when the oxide content of the whole thermal fuse remains unchanged. SOLUTION: The low-melting alloy element 2 is welded between the ends of a pair of lead conductors 1, and the oxide content of the low-melting alloy element is decreased as reaching the end side of the lead conductor and is increased as reaching the center of the low-melting alloy element.
