SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR PRODUCING SOLID ELECTROLYTIC CAPACITOR

WIPO Patent Application WO/2023/243662

A1

Provided is a solid electrolytic capacitor 100 comprising: an element body 110 that includes a superposed body 11 in which a plurality of solid electrolytic capacitor elements 10 are disposed along a first direction T and a sealing resin 20 which is provided around the superposed body 11, and that has a first surface 110e and a second surface 110f which are opposite from each other in a second direction L orthogonal to the first direction T; a first external electrode 120 that is formed on the first surface 110e; and a second external electrode 130 that is formed on the second surface 110f. The plurality of solid electrolytic capacitor elements 10 each include: a positive electrode 40 that has a metal base layer 40a and a porous layer 40b on the metal base layer 40a; a dielectric layer 41 that is provided on a surface of the porous layer 40b; and a negative electrode 43 that is provided on the dielectric layer 41. The negative electrode 43 is electrically connected to the first external electrode 120 on the first surface 110e. The positive electrode 40 is electrically connected to the second external electrode 130 on the second surface 110f. A region R1 sandwiched between respective center parts 43a of negative electrodes 43 of a set of adjacent solid electrolytic capacitor elements 10 is filled with the sealing resin 20.
