In an interrupting device, a CPU temporally calculates a temperature difference between an ambient temperature of an electrical wire and an electrical wire temperature, based on current information indicating a value of current flowing through the electrical wire, and adds the ambient temperature of the electrical wire to the calculated temperature difference. In this way, the CPU temporally computes the electrical wire temperature. In the case where the electrical wire temperature computed by the CPU is greater than or equal to a threshold temperature, a FET turns off and current flowing through the electrical wire is interrupted. The CPU suspends computation of the electrical wire temperature, in the case where the calculated temperature difference is less than a reference temperature difference and the current value indicated by the current information is less than a reference current value.
