Abstract
A capacitor unit of the present invention is configured so that a dielectric layer is provided on a roughened surface of a valve metal foil for an anode, and further, a conductive layer for a cathode, and a charge collecting metal element for a cathode are provided thereon in the stated order. The conductive layer for a cathode has a three-layer structure including a first conductive polymer layer, a conductive adhesive layer, and a second conductive polymer layer that are laminated in the stated order from the dielectric layer side. The capacitor unit of the present invention is produced by laminating the first conductive polymer layer formed on a side of the valve metal foil for an anode, and the second conductive polymer layer formed on a side of the charge collecting metal element for a cathode, with a conductive adhesive layer being interposed therebetween, and compressing the same in a lamination direction.
