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.

Electrochromic element

An electrochromic device is provided. The electrochromic device includes a laminated body having a curved surface shape and an optical lens on a first surface of the laminated body. The laminated body includes a substrate, a first electrode layer on the substrate, an electrochromic layer in contact with the first electrode layer, a second electrode layer facing the first electrode layer, and a solid electrolyte layer between the first electrode layer and the second electrode layer and in contact with electrochromic layer.
