ていた。 Conventionally, in the above-mentioned capacitor, aluminum foil for anode and cathode and separator 2 are used.
A total of four types of materials were wound to form a capacitor element. However, in these methods and structures, it is necessary to wind four types of materials without misalignment, connect the pull-out lead tab to the foil by caulking, etc., and the aluminum foil itself is expensive, and the etched ends etc. must be discarded. There were problems such as large quantities, which led to increased costs, and there were many problems in breaking away from the current structure.

Next, on the metallized aluminum 7, an aluminum oxide 8 serving as a dielectric is metallized in the same area to form an anode electrode 9. Next, as shown in FIGS. 2C and d, high-purity aluminum 7 is metalliconed on one side of the separator 6 and opposite to the metallicon positions shown in a and b to form a cathode electrode 10.
