Zusammenfassung:An electrolytic capacitor includes a capacitor element having: an anode; a dielectric layer covering at least a part of the anode body; a solid electrolyte layer covering at least a part of the dielectric layer; and a cathode lead-out layer covering at least a part of the solid electrolyte layer. The cathode lead-out layer includes a carbon layer covering at least a part of the solid electrolyte layer, a first metal layer covering at least a part of the carbon layer, and a second metal layer covering at least a part of the first metal layer. The first metal layer contains first metal particle, and the second metal layer contains second metal particles and a second binder resin. The first metal layer contains no binder resin, or contains a first binder resin in a volume ratio smaller than a volume ratio of the second binder resin contained in the second metal layer.
