Abstract

Provided is an electrochromic element including: a first electrode (1); a second electrode (2) apart from and opposite to the first electrode (1); an electrolyte layer (5) between the first electrode (1) and the second electrode (2), containing an oxidizable substance or a reducible substance, or both; and at least one of an oxidizable electrochromic layer (6) between the first electrode (1) and the electrolyte layer (5), containing an oxidizable electrochromic compound, and reducible electrochromic layer (9) between the second electrode (2) and the electrolyte layer (5), containing a reducible electrochromic compound, wherein an oxidation potential of the oxidizable substance is nobler than an oxidation potential of the oxidizable electrochromic compound, a reduction potential of the reducible substance is baser than a reduction potential of the reducible electrochromic compound, an oxidation reaction of the oxidizable substance is irreversible, and a reduction reaction of the reducible substance is irreversible.
