Title:
電極箔の製造方法および電解コンデンサの製造方法
Document Type and Number:
Japanese Patent JP7029675
Kind Code:
B2
Abstract:
An electrolytic capacitor has an electrode foil that includes a metal foil containing a first metal, a first dielectric layer disposed on the metal foil, and a second dielectric layer disposed on the first dielectric layer. A method for manufacturing the electrolytic capacitor includes subjecting a roughening treatment to the metal foil and forming the second dielectric layer on a roughened surface of the metal foil by an atomic layer deposition method. The second dielectric layer contains an oxide of a second metal. The method further includes forming the first dielectric layer containing an oxide of the first metal between the metal foil and the second dielectric layer by subjecting the metal foil to an anodization treatment.
