The objective of the current invention is to provide a solid electrolytic capacitor element with low equivalent series resistance. In this solid electrolytic capacitor element, an anode including a porous sintered body, and a dielectric layer are sequentially formed on an anode lead so as to cover a portion of the anode lead. An intermediate layer including polyethylene glycol is formed on the dielectric layer so as to cover an area around the dielectric layer. An electrolyte layer that includes polypyrrole is formed on the intermediate layer so as to cover an area around the intermediate layer. A cathode that includes: a first electrically conductive layer mainly including graphite particles and a second electrically conductive layer mainly including silver particles is formed on the electrolyte layer so as to cover an area surrounding the electrolyte layer.read more
