PROBLEM TO BE SOLVED: To solve a problem on pollution of groundwater eluted by acid rain when a thermal fuse used in an electronic equipment is disposed by land reclamation since a fusible alloy for the thermal fuse has conventionally contained noxious element such as Pb, Cd. SOLUTION: The fusible alloy for the thermal fuse has melting temperature nearly at 90°C without including Pb and Cd and furthermore exactly operates at a predetermined temperature because of a narrow melting temperature region.
