PROBLEM TO BE SOLVED: To provide an alloy type thermal fuse with an operation temperature of 120-150°C capable of securing good operation stability to a heat cycle in spite of use of a fuse element principally consisting of an In-Sn alloy and securing wire drawing with a good yield of the fuse element in spite of a high content of In. SOLUTION: In the fuse element, an alloy composition consists of 52-85% of In and the rest of Sn, and 0.1-7 pts. wt. of one or more kinds of substances selected from Ag, Au, Cu, Ni, Pd, Pt, and Sb are added to 100 pts. wt. of Sn.
