Solid electrolytic capacitor element and method for manufacturing solid electrolytic capacitor element

Abstract

Disclosed is a solid electrolytic capacitor element including a dielectric layer, a first conductive polymer semiconductor layer, a second conductive polymer semiconductor layer and a conductor layer, formed in that order, on a tungsten anode body having an externally protruding lead wire, and the thickness of the thickest portion of the second conductive polymer semiconductor layer on the lower surface opposite the upper surface from which the lead wire protrudes is thinner than the thickness of the thickest portion of the second conductive polymer semiconductor layer on the side surfaces, and the thickness of the second conductive polymer semiconductor layer on the lower surface is greater than 2 μm and less than 15 μm.

Dependencies are inferred from the claim text.
