Electrochromic element and electrochromic light control device

Abstract

Provided is an electrochromic element including: a support; an electrochromic layer over the support; an electrolyte layer over the support; and a sealant resin layer in contact with the electrochromic layer at longitudinal ends of the electrochromic layer in a layer lamination direction, wherein the electrochromic layer contains a polymerized product of an oxidatively color-developable electrochromic composition containing a radical-polymerizable compound, and the sealant resin layer contains a thermosetting material.

Dependencies are inferred from the claim text.
