Abstract:
1. An electrochromic mirror, comprising a transparent substrate; an electrochromic film, that reductively develops color, and has the transparent substrate on or above a surface thereof; a light-reflecting film, that allows transmission of hydrogen atoms or lithium atoms, and is formed on a side of the electrochromic film that is opposite to a side provided with the transparent substrate; a substrate having an electrically conductive area on at least one surface that faces the light-reflecting film; and an electrolyte solution that comprises hydrogen ions and an oxidizable material containing neutral molecules or negative ions and that is sealed between the light-reflecting film and the conductive area of the substrate, wherein (i) the light-reflecting film has electrical conductivity, or, (ii) a transparent electrode film having electrical conductivity is formed between the transparent substrate and the electrochromic film, further comprising a dielectric film that has hydrogen ion conductivity or lithium ion conductivity and is formed between the light-reflecting film and the electrolyte solution to protect said light-reflecting film from corrosion by said electrolyte solution.
