摘要：
A thermal fuse comprises: a first insulating film to which a pair of metal terminals are attached; a fusible alloy located above the first insulating film and connected between the leading end portions of the pair of metal terminals; and a second insulating film located above the fusible alloy and attached to the first insulating film so as to define a space with the first insulating film. The fusible alloy includes an Sn-Bi-In-Zn alloy containing 0.5 to 15 weight% of Bi, 45 to 55 weight% of In and 0.5 to 5 weight% of Zn with the balance being Sn.
