  • Patent number: 7800807
    Abstract: An electrochromic mirror includes an electrochromic film, an electrically conductive reflective film formed at one thickness direction side of the electrochromic film, an electrically conductive film provided at one thickness direction side of the electrochromic film and at a side of the electrically conductive reflective film that is opposite from the electrochromic film, an electrolytic solution containing lithium ions and enclosed between the electrically conductive reflective film and the electrically conductive film, and a reduction reaction compensation unit. In the electrolytic solution, due to applying a voltage such that the electrically conductive film is made positive and electrically conductive reflective film is made negative, the lithium ions move toward the side of the electrochromic film and are provided to a reduction reaction of the electrochromic film. The reduction reaction compensation unit compensates the reduction reaction.
