A backup power-supply device including a control unit is provided. In a case where a main power supply is normal when an ignition is turned on, the control unit controls to turn on or off a charging circuit to charge a capacitor from the main power supply so that a voltage of the capacitor becomes constant at a target voltage and turns off the discharging circuit to stop discharging from the capacitor to a first electronic device. In a case where an abnormality occurs in the main power supply when the ignition is turned on, the control unit turns off the charging circuit to stop charging from the main power supply to the capacitor and turns on the discharging circuit to perform discharging from the capacitor to the first electronic device.
