Abstract
An electric connection boxcomprises an FETfor connection with a power supply B, a substrate side conduction pathconnected with the FETand connecting the FETwith a load L, a diode element D connected with the substrate side conduction pathelectrically and to transfer heat and having a PN junction, and a CPUfor judging whether the voltage drop value between the input/output terminalsandof the diode element D is larger than a threshold or not and delivering an off-command signal to the FETif a judgment is made that the voltage drop value is smaller than the threshold.
