PROBLEM TO BE SOLVED: To provide a fuse device capable of measuring current flowing in a shunt resistor without taking heed of a changing rate of shunt resistor values against temperature changes of the shunt resistor by computation or the like. SOLUTION: By utilization of the fact that voltage fall at a first conductor 205 as the shunt resistor and that at a second conductor 2 of a material having the same resistance temperature coefficient as the first conductor 205 are alike affected by resistance value changes due to equivalent temperature changes, a current for measurement flowing out of the second conductor 2 connected in adjacency to the first conductor 205 is measured. With this, a current to be measured flowing in the first conductor 205 is measured. Even without heed of changing rates of resistance values against temperature changes by computation or the like, a main current flowing out of the first conductor 205 can easily be measured.
