(57) [Problem] In a current fuse, when the surface of the fuse element is covered with a glass glaze layer to prevent oxidation, the fuse element itself may be damaged by heat of glass. Further, since a plurality of current fuses and thermal fuses are mounted on industrial electronic devices and home electric appliances, there is also a problem that reduction in size and size is hindered. SOLUTION: The current fuse 10 has a current fuse element 13 coated with a flux 15 used as a thermal fuse as an antioxidant. Further, the present invention provides the current fuse 10 having a function of a temperature fuse for applying an antioxidant to the current fuse element 13 made of a low melting point alloy material and fusing at a predetermined temperature. |
