PROBLEM TO BE SOLVED: To provide an electrochromic module excellent in transmissivity and a color change contrast, with less power consumption and excellent durability.SOLUTION: An electrochromic module includes a configuration with a lamination of at least two layers of electrochromic cells each having: first and second substrates arranged facing each other at an interval; first and second electrodes disposed on the first and second substrates; a first electrochromic layer containing an oxidation type electrochromic compound formed on the first electrode; a second electrochromic layer containing a reduction type electrochromic compound formed on the second electrode; and an electrolyte disposed between the first electrode and the second electrode. Each substrate on the upper and lower surfaces is the first substrate. At least one of the first substrates on the upper and lower surfaces is transparent. A substrate other than the first substrates on the upper and lower surfaces is transparent. An electrode disposed on a transparent substrate is transparent.SELECTED DRAWING: Figure 2 【課題】透過率や色変化のコントラストに優れ、消費電力が少なく、耐久性に優れたエレクトロクミックモジュールの提供。【解決手段】間隔を置いて互いに対向して設けられた、第１及び第２の支持体と、第１及び第２の支持体に設けられた、第１及び第２の電極と、第１の電極上に設けられた、酸化型エレクトロクロミック化合物を含む第１のエレクトロクロミック層と、第２の電極上に設けられた、還元型エレクトロクロミック化合物を含む第２のエレクトロクロミック層と、第１の電極と第２の電極との間に設けられた電解質と、を有するエレクトロクロミックセルを、少なくとも二つ以上積層した構成を有し、上下表面となる支持体がいずれも第１の支持体であり、上下表面となる第１の支持体は少なくともいずれか一方が透明であり、上下表面となる第１の支持体以外の支持体は透明であり、透明の支持体に設けられた電極は透明であるエレクトロクロミックモジュール。【選択図】図２
