A solid electrolytic capacitor includes a valve acting metal having microfine pores, a dielectric film formed on a surface of the valve acting metal, and a solid electrolyte layer provided on the dielectric film, in which at least a portion of the solid electrolyte layer is of a lamellar structure. In particular, a solid electrolytic capacitor includes an electrically conducting polymer having a specified condensed ring structure containing (1) a solid electrolyte layer containing a sulfoquinone anion having a sulfo anion group and a quinone structure and other anion, and (2) a solid electrolyte layer containing an anthracenesulfonate ion and other anion.
固体电解电容器包括具有微细孔隙的阀门作用金属、形成于阀门作用金属表面的介电膜以及设置在介电膜上的固体电解质层,其中固体电解质层的至少一部分为片状结构。具体而言,固体电解电容器包括具有特定缩合环结构的导电聚合物,其中包含(1)含有磺醌阴离子的固体电解质层,该阴离子具有磺阴离子基团和醌结构以及其他阴离子;以及(2)含有蒽磺酸离子和其他阴离子的固体电解质层。
