PROBLEM TO BE SOLVED: To provide a temperature fuse which can secure meltdown temperature from 175 deg.C or higher to 185 deg.C or lower, and a wire material for a temperature fuse element suitable for manufacturing of this temperature fuse. SOLUTION: The temperature fuse is a temperature fuse, having a fuse element melting at a given temperature, and the fuse element is formed from a fusible alloy, consisting of bismuth of 1 weight% or more and 10 weight% or less, zinc of 3 weight% or more and 13 weight% or less and the rest of tin. Furthermore, a wire material for the temperature fuse element is also formed from a fusible alloy of similar composition. That it to say, by adjusting the bismuth content and indium content in the fusible alloy, a temperature fuse and the wire material are provided with superior fusion temperature characteristics and with moderate strength and ductility.
