A vehicle-mounted power source device includes: a power storage unit; a charging unit; a discharging unit; and a control unit which controls operations of the charging unit and the discharging unit in accordance with an activation signal. When the control unit receives the activation signal, the terminal voltage of the power storage unit becomes the first voltage through a charging operation of the charging unit, and when the control unit finishes receiving the activation signal, the discharging unit starts a discharging operation, and the terminal voltage of the power storage unit is reduced to a second voltage lower than the first voltage. The charging unit applies a third voltage lower than the second voltage to the power storage unit between (i) when the terminal voltage of the power storage unit becomes lower than the second voltage or when a predetermined length of time has elapsed since the terminal voltage of the power storage unit became lower than the second voltage and (ii) when the control unit receives the activation signal again.
