Abstract
It is aimed to provide a fuse element capable of interrupting an electrical circuit while suppressing the formation of carbide when an abnormal current is generated. A fuse element 10 is provided with an insulating base material 3, a conductor layer 1 provided on a surface of the base material 3 and an insulating protection layer 4 provided on a surface of the conductor layer 1. The protection layer 4 has a specific heat of 1.1 J·g−1·K−1 or more and a specific gravity of 1.0 g·cm−3 or more.
Claims9
A fuse element, comprising:
- a base layer comprising an insulating base material;
- a conductor layer provided on a surface of the insulating base material;
- and
- a protection layer formed of an insulating material and provided on a surface of the conductor layer via at least one of the base layer and an adhesive layer, the protection layer having a specific heat of 1.1 J·g−1·K−1 or more and a specific gravity of 1.0 g·cm−3 or more,
- wherein
- the insulating base material of the base layer is provided on both surfaces of the conductor layer,
