Original Abstract Submitted

The occurrence of a ground fault can be detected more accurately. A ground fault detection device is for detecting a ground fault in a conductive path for supply of power from a first power source to a second load in an in-vehicle system. The ground fault detection device includes a voltage detection unit that detects a voltage value of the conductive path, a current detection unit that detects a current value of the conductive path, and a control unit that determines whether or not a ground fault occurred in the conductive path, based on an evaluation value that increases as the voltage value detected by the voltage detection unit decreases, and based on the current value detected by the current detection unit.
