Japanese Unexamined Patent Publication No. 55-28022 discloses a conductive transparent thin film in which a platinum vapor-deposited film is formed on the surface of a base material. Since metals such as platinum are opaque, in order for the deposited film to be transparent, its thickness must be approximately 200 Å or less. In order to further impart conductivity to this, the thickness of the deposited film needs to be 100 to 200 mm thick. Since such a deposited film is very thin, the surface resistance of the base material is at most 10 5 to 10 6 Ω/sq, and the conductivity is poor. in this way.

The vapor deposition is performed by, for example, an electron beam heating method, an ion plating method, a sputtering method, etc. in a high vacuum atmosphere. Although any of these methods can form a deposited thin film with a uniform composition on the substrate, the sputtering method is the most preferred because the variation in composition is particularly small.
