Abstract
Provided is a current fuse that can improve the rating while also preventing explosive scattering of metal in association with arc discharge and enabling reliable cutting off of a circuit. The current fuse (1) includes an insulating substrate (2), a main fuse element (3) disposed on the insulating substrate (2), and a sub-fuse element (4) disposed on the insulating substrate (2) and having a higher melting point than the main fuse element (3). The main fuse element (3) and the sub-fuse element (4) are connected in parallel.
