ABSTRACT:
An alloy type thermal fuse is provided in which a ternary Sn—In—Bi alloy is used, the operating temperature belongs to the range of 130 to 170° C., the overload characteristic and the dielectric breakdown characteristic are excellent, the insulation stability after an operation can be sufficiently ensured, and thinning of a fuse element can be easily realized. A fuse element having an alloy composition in which Sn is larger than 43% and 70% or smaller, In is 0.5% or higher and 10% or lower, and a balance is Bi is used.
