| 摘要 |
A solid electrolytic capacitor includes an oxide dielectric layer, a first electrically conductive polymer layer of polymer of thiophene or its derivative, a second electrically conductive polymer layer of pyrrole, aniline, or derivative thereof formed by chemical polymerization, a third electrically conductive polymer layer of thiophene or its derivative formed by chemical polymerization, a fourth electrically conductive polymer layer of thiophene, pyrrole, aniline, or derivative thereof formed by electrolytic polymerization, and a fifth electrically conductive polymer layer of thiophene, pyrrole, aniline, or derivative thereof formed by chemical polymerization, which layers are sequentially disposed on a surface of a valve metal, and a carbon layer and a silver layer disposed on the fifth layer. |
