The present invention provides a highly reliable vehicular power source system. A hybrid power source (112) is configured with a secondary battery (126) and an EDLC (128) connected in parallel. A first switch (L1) connects the hybrid power source (112) and a lead-acid battery (110) in parallel. A power source controller (114) controls the power supply of the hybrid power source (112) and the lead-acid battery (110). The hybrid power source (112) is connected to a starter (116) for starting the engine of the vehicle, and is connected via the first switch (L1) to an electrical component (122) excluding the starter (116). The lead-acid battery (110) is connected to the electrical component (122) and is connected via the first switch (L1) to the starter (116).
