Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a niobium solid electrolytic capacitor that has a high breakdown voltage and is capable of reducing an ESR (equivalent series resistance), and to provide a method of manufacturing the same. SOLUTION: The niobium solid electrolytic capacitor includes a positive electrode 2 formed of niobium or a niobium alloy; a dielectric layer 3 formed on the surfaces of the positive electrode 2; a conductive polymer layer 5, formed on the dielectric layer 3; and a negative electrode layer 6 formed on the conductive polymer layer 5; and the thickness of the dielectric layer 3 is 75 nm or more. An epoxy silane layer 4 is provided between the dielectric layer 3 and the conductive polymer layer 5. COPYRIGHT: (C)2011,JPO&INPIT
