Abstract
The invention aims at providing a solid electrolytic capacitor having a high capacitance and a small equivalent series resistance (ESR) and a method for manufacturing the same. A solid electrolytic capacitor includes: an anodemade of a valve metal or an alloy thereof; a dielectric layerprovided on the surface of the anode; a first coupling agent layermade of a coupling agent having a molecular structure in which at least two phosphonic acid groups are bonded via an alkyl group, the first coupling agent layerbeing provided on the dielectric layer; a first conductive polymer layerprovided on the first coupling agent layer; and a cathode layerprovided on or above the first conductive polymer layer
