Abstract
Provided is an electrochromic element, including a first electrode, a second electrode, a carrier, and an electrolyte, and an anodic organic electrochromic compound and a cathodic redox substance that are arranged between the first electrode and the second electrode, at least one of the first electrode and the second electrode being transparent, in which: the electrolyte, and the anodic organic electrochromic compound and the cathodic redox substance are mixed; the electrolyte is in contact with the first electrode, the second electrode, and the carrier; the carrier has a redox substance; the reduced form of the redox substance of the carrier is more easily oxidized than the reduced form of the anodic organic electrochromic compound.
