Solid electrolyte capacitor

摘要

To provide a solid electrolytic capacitor capable of high performance, the capacitor including: an anode element having a dielectric film disposed on a surface thereof; a cathode element; and a solid electrolyte interposed between the anode element and the cathode element, the solid electrolyte being a conductive polymer having a first repeat unit (A) expressed by the following formula (1) and a second repeat unit (B) expressed by the following formula (2):;
where L is an arbitrarily replaceable alkylene or silyl group having 2 or 3 carbon atoms; and Rx and Ry are each arbitrarily replaceable alkyl groups having a linear or branched structure and having 1 to 14 carbon atoms, each being different from the other.
