Abstract
A first transparent conductive film is formed on a glass substrate. A second transparent conductive film is formed on the first transparent conductive film with intervention of a protective insulation film. The second transparent conductive film is electrically connected to the first transparent conductive film directly or through pin holes formed in the protective insulation film. An inorganic solid film which manifests the electrochromic phenomenon is formed on the second transparent conductive film.
