Abstract
An electrolytic capacitor element including: a valve-acting metal substrate including a core portion made of metal foil and a porous portion along a surface of the metal foil; a dielectric layer on the porous portion; a solid electrolyte layer on the dielectric layer; and a conductive layer on the solid electrolyte layer, the conductive layer including a carbon layer, the carbon layer containing a carbon filler and a scaly insulating inorganic filler, wherein, in a cut section of the electrolytic capacitor element in a direction perpendicular to a main face of the metal foil, an average of acute angles between a longitudinal direction of a cross-section of the insulating inorganic filler in the carbon layer adjacent to the main face of the metal foil and a longitudinal direction of a cross-section of the metal foil is 0° to 45°.
