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 an anode 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 &#x394;&#x3b3;(=&#x3b3;&#x2212;&#x3b3;) between the hydrogen-bonding component value &#x3b3;[mN/m] of the carbon layer surface and the hydrogen-bonding component value &#x3b3;[mN/m] of the conductive layer surface is within the range of &#x2212;3&#x2266;&#x394;&#x3b3;&#x2266;3 [mN/m].

Solid electrolytic capacitor element, method for manufacturing same, and conductive paste

A conductive paste comprising a conductive powder, an organic binder and a solvent as principal components, wherein the paste also contains at least one selected from the group consisting of N-acylamino acids and salts thereof. The conductive paste has a greatly improved storability without causing separating out or precipitation of the conductive powder even after storing for a prolonged period of time.
