CAPACITOR AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a capacitor which has a superior conductivity of a solid electrolyte layer of a cathode and a low ESR, and its manufacturing method. SOLUTION: A capacitor 10 comprises an anode 11 composed of porous material of valve metal, a dielectric layer 12 formed by oxidizing the surface of the anode 11, and the cathode 13 formed on the dielectric layer 12. The cathode 13 comprises the solid electrolyte layer 13a containing π conjugated conductive polymer, dopant and nitrogen-containing aromatic cyclic compound. COPYRIGHT: (C)2006,JPO&NCIPI
