A control section sets a positive side switching element of a positive side detection section and a negative side switching element of a negative side detection section to ON, thus outputting an ON signal. When the switching elements are set ON, a predetermined current outputted from a positive side constant current source and a negative side constant current source, or a portion of this current, flows through detection resistors. A ground fault decision section decides whether a ground fault has occurred in the positive or the negative side of a direct current power source, based upon the value of an output voltage detected by a positive side voltage detector, or upon the value of an output voltage detected by a negative side voltage detector. Ground faults are accurately detected with a simple structure.
