Method of Producing Metal Oxide Film

摘要

A method of producing a metal oxide film in which the metal oxide film is formed directly onto a surface of a substrate without subjecting the substrate surface to catalytic treatment, and the method which enables to make the obtained metal oxide film even through a simple process even if the substrate has a structural part. The metal oxide film is obtained by bringing a surface of a substrate into contact with a metal oxide film-forming solution that has a metal salt or a metal complex dissolved as a metal source, wherein the metal oxide film-forming solution comprises a reducing agent.
