A ground fault detection apparatus includes a control unit measuring fully charged voltage of a capacitor, a first switch and a first resistor connecting a positive electrode side of a battery to a positive-electrode-side end of the capacitor, a second switch and a second resistor connecting a negative electrode side of the battery to a negative-electrode-side end of the capacitor, a third switch connecting the positive-electrode-side end to ground, a fourth switch connecting the negative-electrode-side end ground, a positive-electrode-side termination resistor connecting the positive electrode side of the battery to the ground, and a negative-electrode-side termination resistor connecting the negative electrode side to ground. The control unit compares charge voltage of the capacitor measured while the first and fourth switches are turned on with charge voltage of the capacitor measured while the second and third switches are turned on.
