ABSTRACT:
A manufacturing method of an anode body of a solid electrolytic capacitor which, for improving the embedded strength of the anode lead with reduced leakage current, successively throws two kinds of valve action metallic powders with different melting-down properties into a single-step press manufacturing die so as to be arranged with the valve action metallic powder whose melting-down property is larger in the neighborhood of the embedded surface of the anode lead.
