PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor which is superior in transient response and maintains a low impedance, up to a high-frequency region. SOLUTION: First anode terminal parts a1 and a2 are formed in both end parts of a valve metal substrate 1. A dielectric oxide coating film 4 is formed, in a region other than regions where the first anode terminal parts a1 and a2 are formed, on a connecting surface to a mounting substrate, of the valve metal substrate 1, and a cathode electrode layer constituted of a solid electrolyte 5 and a conductive member 6 is successively provided on the surface of the film 4 to form cathode parts d1 and d2. A second anode terminal part b1, which is integrally formed with the valve metal substrate 1 and has a surface exposed to a position level with the cathode electrode layer is formed, in a part of the regions forming cathode parts d1 and d2 in the valve metal substrate 1. A dielectric oxide coating film 14 is formed on a surface opposite to the connection surface to the mounting substrate, of the valve metal substrate 1, and a cathode electrode layer, constituting a solid electrolyte 15 and a conductive member 16 is sequentially provided on the surface of the dielectric oxide coating film 14 and a cathode part 20 for transmission line formation is formed.
