Abstract: To spread flux evenly across the entire surface of a rectangular meltable conductor, a protective element includes: an insulating substrate; a heat-generating resistor disposed on the insulating substrate; a first and a second electrodes laminated onto the insulating substrate; a heat-generating element extracting electrode overlapping the heat-generating resistor in a state electrically insulated therefrom and electrically connected to the heat-generating resistor on a current path between the first and the second electrodes; a rectangular meltable conductor laminated between the heat-generating element extracting electrode and the first and the second electrodes for interrupting a current path between the first electrode and the second electrode by being melted by heat; and a plurality of flux bodies disposed on the meltable conductor; wherein the flux bodies are disposed along the heat-generating resistor.

Abstract: A protective element including a substrate having a first insulating member and a concave portion formed thereon, a heating body layered on the concave portion of the substrate, a second insulating member layered on the substrate so as to cover at least covering the heating body, first and second electrodes layered on a surface of the substrate on which the second insulating member is layered, a heating body electrode layered on the second insulating member so as to be superimposed with the heating body, and electrically connected to a current path between the first and the second electrodes as well as onto and the heating body, and a low-melting point metal layered from the heating body electrode toward the first and the second electrodes configured to cause a blowout of the current path between the first and the second electrodes by heating.
