CAPACITOR AND METHOD FOR MANUFACTURING SAME

摘要

Disclosed is a capacitor having high capacity, low ESR (equivalent series resistance) in high frequency range and low leakage current. The capacitor is obtained by the following procedure: an oxide coating film is formed by electrolytically oxidizing a base surface containing a valve metal element; then a solution, in which metal ions and an organic base are dissolved, is reacted with the oxide coating film and then the resulting is fired, thereby obtaining a complex oxide film; and after that a solid electrolyte layer is formed on the complex oxide film and a conductor layer is formed thereon. Also disclosed are a method for producing such a capacitor and an electronic device and the like using such a capacitor.
