Abstract
A solid electrolytic capacitor having an electrolytic layer containing at least two types of ionic liquids and a conductive polymer is provided. Preferably, the ionic liquids include at least one type of ionic liquid for supplying an excellent impedance characteristic and at least one type of ionic liquid for supplying an excellent withstand voltage characteristic. Thus, a solid electrolytic capacitor exhibiting a high withstand voltage and an excellent impedance characteristic can be obtained.
