摘要： A solid electrolytic capacitor of the present invention includes a positive electrode body, a dielectric layer disposed on the surface of the positive electrode body, a solid electrolyte layer disposed on the surface of the dielectric layer, a negative electrode layer disposed on the surface of the solid electrolyte layer, a positive electrode terminal electrically connected to the positive electrode body, and a negative electrode terminal electrically connected to the negative electrode layer, wherein the negative electrode layer includes a carbon layer and a conductor layer, and the carbon layer contains carbon particles and a benzene compound shown by the chemical formula 1. The whole is covered with facing resin while exposing the positive electrode terminal led out of the positive electrode body and the negative electrode terminal led out of the negative electrode layer. With this configuration, the carbon layer formed is fine and uniform. Accordingly, the contact resistance between the solid electrolyte layer and the carbon layer is reduced, and the contact resistance between the carbon layer and the conductor layer. As a result, it is possible to obtain a solid electrolytic capacitor assuring excellent equivalent series resistance characteristic and capacity utilization factor. Chemical formula 1 where each of R1, R2, R3, and R4 has H, OH group, COOH group, or alkyl group

摘要： A solid electrolytic capacitor of the present invention has a structure where respective anode sections of capacitor elements are joined to an anode lead frame by resistance welding via a through hole formed in the anode lead frame. Current thus collects to the through hole during the welding to break a dielectric oxide film layer to expose aluminum foil, and the molten aluminum collects into the through hole. Stable welding work is therefore allowed without splashing the aluminum, and a solid electrolytic capacitor having high welding strength, high reliability, and reduced ESR can be obtained.

摘要： A disclosure is made on a solid electrolytic capacitor, which facilitates an assembly work with simple construction to lead to a reduction of cost, realizes excellent equivalent series resistance characteristics and makes a thin configuration possible, and a manufacturing method thereof. With the solid electrolytic capacitor of the present invention, a cathode lead frame has a connecting member to connect integrally with a cathode member of a capacitor element stack body on the side surface of a capacitor element extending in the thickness direction thereof. Capacitor elements, each provided with a through hole on an anode member, are stacked on top of each other in layers and connections between capacitor elements are achieved by disposing an anode lead frame between layers. Accordingly, when a plurality of anode members are joined to the anode lead frame via a through hole provided on respective anode members of capacitor elements, stabilized welding work is allowed to be performed without any of molten aluminum foil to be released outside.
