SOLID ELECTROLYTIC CAPACITOR AND METHOD OF MANUFACTURING THE SAME

According to one aspect, a solid electrolytic capacitor includes an anode body made of a valve metal, a dielectric layer formed on the anode body, a solid electrolyte layer formed on the dielectric layer, and a cathode body layer formed on the solid electrolyte layer. The solid electrolyte layer includes a first layer including a first conductive polymer doped with a single-molecule dopant and a second conductive polymer composed of a self-doped conductive polymer including a plurality of side chains containing functional groups capable of being doped. And a second layer formed on the first layer and including a third conductive polymer doped with a polymer dopant; the first conductive polymer is in contact with a third conductive polymer (second layer). 根据一个方面，固体电解电容器包括由阀金属制成的阳极体、在阳极体上形成的介电层、在介电层上形成的固体电解质层以及形成在固体电解质层上的阴极体层。固体电解质层包括包含掺杂有单分子掺杂剂的第一导电聚合物和由包含多个含有能够被掺杂的官能团的侧链的自掺杂型导电聚合物构成的第二导电聚合物的第一层，以及在第一层上形成并且包含掺杂有聚合物掺杂剂的第三导电聚合物的第二层；第一导电聚合物与第三导电聚合物(第二层)接触。
