Document Type and Number:
WIPO Patent Application WO/2024/004721
Kind Code:
A1
Abstract:
A capacitor element included in this solid electrolytic capacitor includes: an anode body which has a porous portion and has a first section including a first end part and a second section including a second end part; a dielectric layer; a cathode section which covers at least a part of the dielectric layer in the second section; and a separation section which is positioned between the first end part and the second end part of the anode body and insulates the first section and the cathode section from each other. The cathode section includes at least a conductive polymer layer. The conductive polymer layer has an inner layer filling voids of the porous portion and an outer layer protruding from a main surface of the anode body having the dielectric layer. The separation section has an end part A located on the first end part side and an end part B located on the second end part side. When the length from the end part B to an end part of the cathode section located on the second end part side is defined as L, the porous portion has a filling rate of 46% or higher in a region C included within 0.05 L from the end part B.
