Electrochromic mirror

The present invention provides an electrochromic mirror (10), comprising a transparent substrate (12); an electrochromic film (14) that develops color reductively having the transparent substrate on or above the surface thereof; a light-reflecting film (16) allowing transmission of hydrogen or lithium atoms formed on the side of the electrochromic film opposite to the transparent substrate; a substrate (17) having an electrically conductive area (22) at least on one surface facing the light-reflecting film; and an electrolyte solution (24) at least containing a hydrogen ion 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 (15) having a hydrogen or lithium ion conductivity formed between the light-reflecting film and the electrolyte solution.
