SOLID-STATE ELECTROLYTIC CAPACITOR AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To reduce equivalent series resistance (ESR) and equivalent series inductance (ESL) as much as possible in a foil winding type solid electrolytic capacitor. SOLUTION: The solid electrolytic capacitor is made by forming a solid electrolyte containing conductive polymer on a capacitor element that is wound with an anode electrode foil 11 with an oxide film and a cathode electrode foil 12 with a separator 13 in between. The end 11a of the anode electrode foil 11 is protruded by a specified width from one end 13a side of the separator 13, and an anode electrode lead is formed on one end face side of the capacitor element. The end 12b of the cathode electrode foil 12 is protruded by a specified width from the other end 13b side of the separator 13, and a cathode electrode lead is formed on the other end face side of the capacitor element.
