Abstract
The invention provides a solid electrolytic capacitor element, comprising a metal oxide layer, an electroconductive polymer layer, a carbon paste layer and a silver paste layer sequentially formed on surface of a valve-acting metal material, wherein thickness of the silver paste layer is within a range of 5 to 20 μm and the mass ratio of silver contained in the silver paste layer is within a range of 84 to 94%. According to the invention, a solid electrolytic capacitor having good electric properties such as ESR (equivalent series resistance) and LC (leakage current) and good reliability can be produced.
