Abstract
An electrically conductive polymer layer of a solid electrolytic capacitor that coats a dielectric layer that coats an anode. An anode lead projects outwardly from the anode through the dielectric layer, and the electrically conductive polymer layer is separated by the dielectric layer form the anode lead. The electrically conductive polymer layer has a thicker portion than a remaining portion thereof and the thicker portion extends at least in the vicinity of the anode lead, and the thicker portion is bounded with the remaining portion so that a sloped-boundary loop between the thicker portion and the remaining portion extends to be parallel to a flat plane perpendicular to a direction along which the anode lead projects through the dielectric layer, whereby the thicker portion continuously extends close to the anode lead than the remaining portion.
