  "textContent": "A ground fault detection device includes: a capacitor operating as a flying capacitor; a first switching unit for switching between a state in which a positive electrode side of a battery and a first electrode plate of the capacitor are connected in series via a resistance, and a state in which the first electrode plate of the capacitor is connected to the ground via a measurement resistance; a second switching unit for switching between a state in which a negative electrode side of a high-voltage battery and a second electrode plate of a detection capacitor are connected in series via a resistance, and a state in which the second electrode plate of the detection capacitor is connected to the ground via the resistance; a control unit for controlling the first switching unit and the second switching unit; and an offset voltage divider circuit that divides and offsets the voltage generated in the measurement resistance. The control unit has a first port for receiving an input of a voltage generated in the measurement resistance and a second port for receiving an input of a voltage output from the offset voltage divider circuit.",
