Abstract:
An electrode foil includes a base made of foil of valve metal, and a rough surface layer made of valve metal provided on a surface of the base. The rough surface layer includes plural tree structures extending d from the base. Each of the tree structures includes plural particles of valve metal linked together, and is branched into plural twigs. This electrode foil provides an electrolytic capacitor with a small size and a large capacitance.
