1. A method of manufacturing a composite oxide thin film, comprising(i) providing a work electrode and an opposite electrode immersed in an electrolytic solution, said work electrode comprising a first metal, and said electrolytic solution comprising at least one reactive component which is reactive with said work electrode and contains ions of at least one metal other than the first metal in said work electrode;

  • (ii) energizing said work electrode at a solution temperature of at least 100°

    C. and under a pressure of at least saturated vapor pressure of the solution, thereby reacting said reactive component with said work electrode and forming a composite oxide thin film which contains oxides of said first metal and said metal other than the first metal.
