Abstract
A protective element is provided that is capable of stopping heat generation of a heat generation resistor after all of fuse elements are surely blown out in a case where the power is distributed from a specific power distribution path. The protective element can be configured to control blowout times of a plurality of respective fuse elements in such a manner that other fuse elements are blown out prior to the blowout of a specific fuse element in a case where the power is distributed from the specific power distribution path connected with the specific fuse element among the plurality of fuse elements.

A protective element comprising:
- a heat generation member for generating heat by distribution of power thereto;
- and
- a plurality of fuse elements, disposed between a plurality of electrodes serving as inputs of power distribution paths, capable of being blown out by the heat generated by the heat generation member to cut off an electric current;
- wherein when the power is distributed from a specific power distribution path connected with a specific fuse element among the plural fuse elements, blowout times of the respective plural fuse elements are controllable in such a manner that other fuse elements are blown out prior to the specific fuse element.
