PROBLEM TO BE SOLVED: To perform cut-off operation with less heat with a smaller number of components.SOLUTION: The protective element includes: an exothermic body and an insulating layer, formed by laminating on an insulating substrate; a plurality of electrodes formed on the insulating substrate or the insulating layer; a conductive heat sensitive metal, disposed over the plurality of electrodes, part of which is fixed. By changing a shape of the head sensitive metal by heat of the exothermic body, a connection state is made to be open.SELECTED DRAWING: Figure 2 |
