An electrochromic element is provided that includes a first substrate and a second substrate that are arranged to oppose each other, a first transparent electrode that is formed on a surface of the first substrate facing the second substrate, a second transparent electrode that is formed on a surface of the second substrate facing the first substrate, and a coloration layer that is arranged between the first transparent electrode and the second transparent electrode. The coloration layer includes an electrochromic material and an electrolyte, and a pattern or a concentration gradient of the electrochromic material is formed in at least a part of the coloration layer. |
