Abstract
A capacitor having a high degree of electric strength, a high electrostatic capacity, and a low ESR, which can be readily downsized, is provided. The capacitor according to the present invention includes an anode made of porous valve metal, a dielectric layer formed by oxidizing the surface of the anode, and a solid electrolyte layer formed on the surface of the dielectric layer. The solid electrolyte layer includes a π conjugated conductive polymer, a polyanion, and an ion-conductive compound.
