In a thermal cut-off fuse of the type in which a resilient contactor interposed between the electrodes opposed to each other inside a housing is bulged with the pressure resulting from insertion of a thermal pellet inside the housing so as to establish an electric circuit between the electrodes, desired reduction in the contact resistance between the contactor and the electrodes is accomplished by the improvement which comprises having formed on each of the opposite surfaces of the contactor confronting the opposed electrodes a plurality of raised contacts adapted so that all the raised contacts will remain in fast contact with the electrodes so long as the thermal pellet retains its solid state.
