PROBLEM TO BE SOLVED: To provide a multifunctional ceramic fuse and a ceramic fuse package. SOLUTION: A ceramic fuse 1, a ceramic substrate 4, a thermal fuse element 3 provided on the ceramic substrate 4, and a ceramic substrate 4 disposed in a region overlapping the thermal fuse element 3 as seen through a plane. The heating resistor 5, the current fuse element 6 provided on the ceramic substrate 4, which blows when the current value of the flowing current reaches a predetermined value or more, and the temperature provided on the ceramic substrate 4 are higher than the predetermined temperature. In this case, a low melting point alloy 7 is provided. [Selection] Figure 1 |
