An object of the present invention is to provide a novel electrochromic device (ECD). An electrochromic device (ECD) including two metal complex-based electrochromic thin films acting individually as an action electrode and a counter electrode is disclosed. (I) One of the two metal complex-based electrochromic thin films is a plurality. A membrane of a cathode-colored metallo supermolecular polymer comprising at least one organic ligand having a metal coordination position and at least one transition metal and / or metal ion of a lanthanoid metal, at least one organic ligand and metal. The ions are arranged alternately, and the other of the two metal complex-based electrochromic thin films is represented by the formula: M (II) 3 [Fe (III) CN 6 ] 2 (in the formula, M = Fe, Ni or Zn). An anode-colored metal hexacyanoferrate (MHCF) film, the (ii) electrochromic device is a first conductive substrate, a cathode-colored metallo supermolecular polymer film, an electrolyte, an anode-colored metal hexacyanoferrate (MHCF). ) And the second conductive substrate are arranged in this order. |
