Abstract
Provided is an electrochromic element, including: a first electrode and a second electrode, at least one of the first electrode and the second electrode being transparent; a third electrode; and an electrolyte, an anodic organic electrochromic material, and a cathodic organic electrochromic material that are arranged between the first electrode and the second electrode, in which the third electrode is electrically connectable to at least one of the first electrode and the second electrode via the electrolyte, and in which the third electrode has an effective area that is larger than an effective area of the first electrode and an effective area of the second electrode.
