Abstract
A method for forming a titanium oxide film that can be formed on a surface of a base material without a heating step. In Step, a surface of a molded product (base material) composed of a cyclic olefin-based resin is irradiated with ultraviolet light in an air atmosphere. In Step, the base material is immersed in a mixed liquid of an aqueous solution of titanium chloride and a nitrite ion-containing aqueous solution. A titanium oxide film grows by repeating oxidation of a titanium ion. In Step, the base material is pulled out from the mixed liquid, and then washed to stop the reaction. The film thickness can be controlled by controlling this immersion time. In Step, the base material after washing is dried at room temperature.
