Abstract:
An electrochromic element is provided. The electrochromic element includes a first electrode, a second electrode facing the first electrode with a gap therebetween, and a color developing layer disposed between the first electrode and the second electrode. The color developing layer includes an electrochromic compound that develops and discharges color by a redox reaction and a compound having an adsorption group adsorptive to the first electrode.
