Abstract:
An electrically conductive polymer layer of a solid electrolytic capacitor, said electrically conductive polymer layer coating a dielectric layer coating an anode with an anode lead which projects outwardly from said anode through said dielectric layer, and said electrically conductive polymer layer being separated by said dielectric layer from said anode lead,wherein said electrically conductive polymer layer has a thicker portion than a remaining portion thereof and said thicker portion extends at least in the vicinity of said anode lead, and said thicker portion is bounded with said remaining portion so that a sloped-boundary loop between said thicker portion and said remaining portion extends to be parallel to a flat plane perpendicular to a direction along which said anode lead projects through said dielectric layer, whereby said thicker portion continuously extends closer to said anode lead than said remaining portion, andwherein said thicker portion has a first thickness which is thicker by 1-40 micrometers than a second thickness of said remaining portion and said second thickness is 0.05-10 micrometers.
