CAPACITOR AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To increase the surface area of a dielectric and avoid adverse influence of an electrode metal by adhering polymer conductor-made electrodes to both sides of the dielectric where its one side has the same surface shape as that appearing by close contact to the surface of the electrode metal and the other side has the same surface shape as that of the electrode metal. SOLUTION: A capacitor has electrodes made from a polymer conductor formed on both sides of the dielectric. One side of the dielectric has the same surface shape as that appearing by close contact to the surface of a electrode metal such as porous etched foil 5 and the other side has the same surface shape as that of the electrode metal. The one side of the dielectric has copied porous structure of the etched foil 5 of the electrode metal, and the back side has a mold shape to this structure. The electrode metal uses an etched Al foil. The polymer conductor-made electrodes are adhered to both sides of the dielectric and the polymer conductor uses polypyrrole 7, 8.
