PROBLEM TO BE SOLVED: To provide a multifunctional ceramic fuse and a ceramic fuse package. SOLUTION: A ceramic fuse 1 includes: a ceramic substrate 4; a thermal fuse element 3 provided on the ceramic substrate 4; a heating resistor 5 provided in the ceramic substrate 4 and disposed in a region which overlaps the thermal fuse element 3 in planar perspective view; a current fuse element 6 which is provided in the ceramic substrate 4 and is fused when a current value of a current flowing therein becomes a predetermined current value or more; and a low-melting alloy 7 which is provided on the ceramic substrate 4 and is fused when its temperature becomes a predetermined temperature or more.
