PROBLEM TO BE SOLVED: To provide an alloy type thermal fuse in which excellent overload characteristics and breakdown strength characteristics are attained, the insulation safety after an operation can be sufficiently assured, and a fuse element can be easily thinned. SOLUTION: A fuse element having an alloy composition in which Sn is larger than 25% and 44% or smaller, Bi is larger than 1% and smaller than 20%, and In is larger than 55% and 74% or smaller is used.
