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 Δγh (=γh2−γh1) between the hydrogen-bonding component value γh1 [mN/m] of the carbon layer surface and the hydrogen-bonding component value γh2 [mN/m] of the conductive layer surface is within the range of −3≦Δγh≦3 [mN/m].
A solid electrolytic capacitor element which is provided, on a surface of an anode body, with at least a dielectric layer, a solid electrolyte layer, a carbon layer containing a first resin component, and a conductive layer containing a second resin component, wherein
A method of manufacturing a solid electrolytic capacitor element which is provided with, on a surface of an anode body, at least a dielectric layer, a solid electrolyte layer, a carbon layer, and a conductive layer,
A conductive paste for forming, in a solid electrolytic capacitor element, a conductive layer that is disposed on a carbon layer containing a hydroxyl group-containing resin component, wherein
