    摘要： 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.

    摘要： The invention provides a solid electrolytic capacitor which can suppress increase of a leakage current due to a heat load, and a method for producing the solid electrolytic capacitor. The solid electrolytic capacitor includes an anode body, a dielectric layer formed on a surface of the anode body, a conductive polymer layer formed on the dielectric layer, and a cathode layer formed on the conductive polymer layer. The dielectric layer contains at least one metal element which is selected from the group consisting of tungsten (W), molybdenum (Mo), vanadium (V) and chromium (Cr) and which has a concentration distribution in a direction of the thickness of the dielectric layer (i.e. in a direction from the cathode side to the anode side of the dielectric layer) so that the concentration of the metal element is maximized at an interface between the dielectric layer and the conductive polymer layer.
