1. A solid electrolytic capacitor comprising:

  • a valve action metal body as an anode side electrode;

    an oxide film as a dielectric obtained by oxidizing a surface of said valve action metal body;

    an electron donor organic compound layer formed of an organic compound having an electron donor group covering an entire surface of said oxide film, said electron donor organic compound excluding an ionic surface active agent, a silane coupling agent, an aluminum coupling agent and a titanium coupling agent; and

    a conductive polymer layer as a solid electrolyte layer covering an entire surface of said electron donor organic compound layer.
