PROBLEM TO BE SOLVED: To provide a capacitor power supply device, a voltage monitoring device, a voltage monitoring method, and a method of manufacturing a capacitor power supply device, capable enhancing a measurement accuracy of a voltage of a capacitor.SOLUTION: In calibration processing, a capacitor unit 50 is detached from end part terminals 35A and 35B, that is, individual capacitors 51 are not connected to terminals 35. A predetermined voltage (a known voltage) Vis applied between the end part terminals 35A and 35B. Among bypass switches Sof a bypass circuit 22, a bypass switch Sconnected with one or continuous two or more terminals 35 from the end part terminal 35A side of a positive electrode is turned on. Terminal voltages V-Vother than the end part terminal 35A of the negative electrode are acquired, and those are stored as correction information. |
