PURPOSE:To improve the adhesion of each film constituting multilayered film to each other in a glass formed by laminating thin metal oxide film by the sol-gel method, by interposing thin metal oxide film having an intermediate compsn. of the outermost layer and the inner different metal oxide film between at least the outermost layer and the inner different metal oxide film. CONSTITUTION:The glass is one having optical multilayered thin film formed by laminating thin metal oxide film on the glass by the method described hereunder. Namely, thin metal oxide film having an intermediate compsn. of the outermost layer and the inner different thin metal oxide film is interposed between at least the outermost layer and the inner metal oxide film, wherein these thin metal oxide films are prepd. by the hydrolysis of coated film of metal alkoxide soln. The thin metal oxide film having the intermediate compsn. is constituted of at least two kinds among SiO2, TiO2, ZrO2, Al2O3, and B2O3. |
