Abstract
A protective element achieves oxide film removing functionality in a flux enabling quick melting of a meltable conductor even when the heating temperature of a heating element is raised rapidly. Protective element includes an insulating substrate, heat-generating resistor laminated onto the insulating substrate, insulating member covering the heat-generating resistor, first and second electrode laminated onto the insulating substrate, heat-generating element extracting electrode laminated onto the insulating member so as to overlap the heat-generating element and electrically connected to the heat-generating element on a current path between the first and second electrodes, meltable conductor which is laminated above the heat-generating element extracting electrode between the first and second electrode which interrupts the current path between the first and second electrode by melting due to heat, and oxide film removing material for removing oxide film generated on the meltable conductor, the oxide film removing material having a plurality of different activation temperatures.
