Abstract
An electrochromic element including: a first electrode; a second electrode that is opposed to and apart from the first electrode; and an electrolyte that is between the first electrode and the second electrode, wherein the first electrode includes a polymerized product of an electrochromic composition that includes a radical-polymerizable compound including a triarylamine backbone, and wherein the second electrode includes a compound represented by General Formula (I) where R1 and R2 each denote a hydrogen atom, an aryl group including 14 or less carbon atoms, a heteroaryl group including 14 or less carbon atoms, a branched alkyl group including 10 or less carbon atoms, an alkenyl group including 10 or less carbon atoms, a cycloalkyl group including 10 or less carbon atoms, or a functional group that is capable of binding to a hydroxyl group; n and m each denote 0 or an integer of from 1 through 10; and X− denotes a charge-neutralizing ion.
