Title:

SOLID ELECTROLYTIC CAPACITOR ELEMENT, METHOD FOR MANUFACTURING SAME, AND CONDUCTIVE PASTE

Document Type and Number:

WIPO Patent Application WO/2013/111438

Kind Code:

A1

Abstract:

Provided is a solid electrolytic capacitor element which is reduced in ESR deterioration due to thermal shock and suppressed in variation in ESR changes, while having good initial characteristics of ESR. This solid electrolytic capacitor element is provided, on the surface of a positive electrode body, with at least a dielectric layer, a solid electrolyte layer, a carbon layer that contains a first resin component and a conductive layer that contains a second resin component. Both of the first resin component and the second resin component have a hydroxyl group, and the difference between the hydrogen-bonding component value γh 1 [mN/m] of the carbon layer surface and the hydrogen-bonding component value γh 2 [mN/m] of the conductive layer surface, namely ∆γh (= γh 2 - γh 1) is within the range of -3 ≤ ∆γh ≤ 3 [mN/m].
