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 10 according to the present invention includes an anode 11 made of porous valve metal, a dielectric layer 12 formed by oxidizing the surface of the anode 11, and a solid electrolyte layer 13 formed on the surface of the dielectric layer 12. The solid electrolyte layer 13 includes a À conjugated conductive polymer, a polyanion, and an ion-conductive compound. |
