Title:
SOLID ELECTROLYTIC CAPACITOR AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2010135750
Kind Code:
A
Abstract:

To provide a solid electrolytic capacitor excellent in high-frequency characteristics of equivalent series resistance (ESR).

The solid electrolytic capacitor includes a positive electrode element 11, a positive electrode lead 12 in close contact with an outer surface of the positive electrode element 11, a dielectric layer 13 formed on a surface of the positive electrode lead 12 and a negative electrode layer 15 formed on a surface of the dielectric layer 13. A plurality of openings are formed in the positive electrode lead 12 so as to pass through the positive electrode lead 12. Specifically, the positive electrode lead 12 is constituted of a metal plate having a plurality of through-holes and is in close contact with the outer surface of the positive electrode element 11 in a state that the plurality of through-holes are opened toward the positive electrode element 11.
