A method for producing a high refractive index film and a high refractive index film comprising a step of producing a film made of a germanium compound having a Ge-Ge bond as a main chain, and firing the film in a vacuum or in an inert gas atmosphere Process. As a result, a high refractive index thin film that is soluble in a solvent, has high moldability and film formability, has a high refractive index of 1.8 or more, and 2.3 or more, and is chemically stable, and so on. A method for producing a high-refractive index thin film can be provided. |
