A thermal cut-off fuse of the class wherein the electric continuity between electrodes disposed inside a housing is maintained by conductor means at normal service temperatures and broken by the conductor means being fractured when the ambient temperature reaches a fixed level is improved by having the conductor means made of a metal capable of liquefying before the ambient temperature reaches the fixed level mentioned above and providing a thermal pellet faithfully fusible at the fixed level of temperature for the purpose of supporting in position the conductor means serving to maintain the electric continuity between the electrodes at normal service temperatures and thereby allowing the electric continuity between the electrodes to be broken at the fixed level of temperature by the thermal pellet being melted and deprived of its role of supporting the conductor means.
