Abstract
An optical product according to the present invention includes a transparent base material, and a multilayer film including a dielectric film and an ITO film. The multilayer film is formed on one face or two faces of the transparent base material. The physical thickness of the ITO film is not less than 3 nanometers and not greater than 7 nanometers. The ITO film can be formed by vapor deposition with plasma treatment.
