Title: ELECTROLYTIC CAPACITOR AND METHOD FOR PRODUCING SAME
Abstract:
Provided is an electrolytic capacitor that comprises: a positive electrode; a dielectric layer formed on the positive electrode; a first conductive polymer layer that covers at least a part of the dielectric layer; and a second conductive polymer layer that covers at least a part of the first conductive polymer layer. The first conductive polymer layer is provided with: a P1 layer that includes a first conductive polymer and a first dopant and that covers at least a part of the dielectric layer; and an S layer that is formed on the P1 layer and that includes a first silane compound. The second conductive polymer layer includes a second conductive polymer, a second dopant, and a basic compound. As a result, the ESR of the electrolytic capacitor is reduced.
