Provided is a vehicle-mounted power supply system that multiplexes power supplies in a vehicle and reliably supplies power of a voltage varying from a high voltage to a low voltage, without using a lead battery. A vehicle-mounted power supply system 1 according to the present invention is provided with a primary power storage device 2, a secondary power storage device 3, and a power generation device 4. The primary power storage device 2 has a high-voltage output terminal 11 and a low-voltage output terminal 12. The power generation device 4 supplies power to the primary power storage device 2 and the secondary power storage device 3. The power supply system 1 is further provided with: a first switch 21 disposed between the power generation device 4 and the primary power storage device 2; a second switch 22 disposed between the power generation device 4 and the secondary power storage device 3; and a third switch 23 disposed between the low-voltage output terminal 12 of the primary power storage device 2 and the output terminal 13 of the secondary power storage device. The power supply system 1 is characterized in that the power generation device 4 is a power generator 42 provided with an inverter 41, or a power generator that can output a variable voltage.
