An in-vehicle power supply device (10) is used in an in-vehicle power supply system (100). An in-vehicle power supply system (100) is provided with a battery (20), a power path (21) to which power from the battery (20) is supplied, and a capacitor (22) connected to the power path (21). An in-vehicle power supply device (10) is provided with a mechanical system main relay (first SMR (51)), a parallel circuit (53), and a second relay (56). A system main relay (first SMR (51)) is provided in the power path (21) on the battery (20) side of the capacitor (22). The parallel circuit (53) configures a structure in which the first relay (54) and the resistor unit (55) are connected in series, and is provided in parallel with a system main relay (first SMR (51)). The second relay (56) is provided in parallel with the resistor unit (55).
