摘要：
本发明的电解电容器具有：阳极体；在阳极体上形成的电介质层；覆盖电介质层的至少一部分、并且包含第1导电性高分子的第1导电性高分子层；和覆盖第1导电性高分子层的至少一部分、并且包含第2导电性高分子的第2导电性高分子层。第1和第2导电性高分子层各自还包含具有磺化度S1的第1高分子掺杂剂。第1或第2导电性高分子层(或者第1和第2导电性高分子层)还包含具有磺化度S2的第2高分子掺杂剂，并且S1＜S2。第1导电性高分子层与第2导电性高分子层的第2高分子掺杂剂的组成不同。
摘要（英）：

An electrolytic capacitor includes an anode body, a dielectric layer formed on the anode body, a first conductive polymer layer covering at least a part of the dielectric layer, and a second conductive polymer layer covering at least a part of the first conductive polymer layer. The first conductive polymer layer includes a first conductive polymer. The second conductive polymer layer includes a second conductive polymer. The first conductive polymer layer and the second conductive polymer layer each further include a first polymer dopant having a sulfonation degree of S1. At least one of the first conductive polymer layer and the second conductive polymer layer further includes a second polymer dopant having a sulfonation degree of S2. The sulfonation degree of S1 and the sulfonation degree of S2 satisfy a relation of S1
