A ground fault detection device (10) is used in an in-vehicle system (100). An in-vehicle system (100) is provided with a power supply unit (90), a power storage unit (91), a conductive path (80), and a cutoff unit (74). The conductive path (80) has a first conductive path (81), a second conductive path (82), and a third conductive path (83). The cutting section (74) has a first cutting section (75) and a second cutting section (76). The second load (72) is connected to one of the second conductive path (82) and the third conductive path (83), and the third load (73) is connected to the other of the second conductive path (82) and the third conductive path (83). The grounding detection device (10) is provided with a detection unit (a current detection unit (13) and a control circuit (14)) for detecting grounding of at least one of the second conductive path (82) and the third conductive path (83).
