A capacitor power source 1 including a plurality of capacitors comprises: an inflection-point voltage detection circuit (11) for detecting the inflection-point voltage of the capacitor based on a set voltage Vbot; an overvoltage detection circuit (12) for detecting the overvoltage Vful of the capacitor; and an initialization circuit (13) for putting charging current of the capacitor into bypass operation using initialization voltage Vini when an initialization mode is selected, wherein charging/discharging control is performed such that a discharging stop signal is generated based on a detection signal of the inflection-point voltage of any one of the plurality of capacitors, a charging stop signal is generated based on a detection signal of the overvoltage of any one of the plurality of capacitors, and an end signal of the initialization charging is generated based on a plurality of bypass operation signals.
