Patent ID: 7643201

Claim:
An electrochromic mirror, comprising: a transparent electrode film that is capable of transmission of light and has electrical conductivity; an electrochromic film that is formed at one thickness direction side of the transparent electrode film and is colored due to being subjected to a reduction reaction; a light reflective film that is formed from silver or an alloy containing silver and that reflects light that has transmitted through the transparent electrode film and the electrochromic film; a transparent lithium ion transmissive film that is provided between the electrochromic film and the light reflective film, and that transmits lithium ions and imposed diffusion of silver from the side of the light reflective film to the side of the electrochromic film; an electrically conductive film having electrical conductivity that is provided at the one thickness direction side of the transparent electrode film and at a side of the light reflective film that is opposite from the lithium ion transmissive film; and an electrolytic solution that comprises lithium ions and is enclosed between the light reflective film and the electrically conductive film, and in which, due to application of a voltage such that the electrically conductive film is made positive and the transparent electrode film is made negative, the lithium ions move toward the side of the electrochromic film and are provided to the reduction reaction of the electrochromic film.
