Provided is a vehicle-mounted power supply device detecting connection with an external power source and charging a power storage unit by stepping up a supply voltage based on the external power source. A vehicle-mounted power supply device includes an external terminal to which a power supply path from an external power source is connectable, a detection unit detects that the power supply path is connected to the external terminal, and a power supply circuit unit allows for flow of a current from the external terminal side toward the second conduction path side at least when the power supply path is connected to the external terminal. The control unit controls a step-down operation and a step-up operation of the voltage conversion unit, and causes the voltage conversion unit to perform the step-up operation when connection between the external terminal and the power supply path is detected by the detection unit.
