Document Type and Number:
WIPO Patent Application WO/2023/162904
Kind Code:
A1
Abstract:
This solid electrolytic capacitor element comprises: a positive electrode foil having a porous portion on a surface layer thereof, and also including a first portion including a first end and a second portion including a second end opposite to the first end; a dielectric layer formed on the surface of the porous portion; and a solid electrolyte layer covering at least a portion of the dielectric layer. The solid electrolytic capacitor element has an insulating region containing a cured product of a resin composition between the first end and the second end of the positive electrode foil. In the insulating region, pores of the porous portion are filled with the cured product. The resin composition includes an insulating resin material and an additive that modifies the insulating resin material. The content of the additive in the resin composition is at least 3 mass%. The glass transition point of the cured product is at least 230 °C.
