Zusammenfassung:An electrochromic element including: a first electrode; a second electrode disposed to face the first electrode with a gap between the first electrode and the second electrode; a first electrochromic layer disposed on or above the first electrode, including conductor or semiconductor nano-structures and an electrochromic compound; and an electrolyte layer including an electrolyte, disposed between the first electrochromic layer and the second electrode, wherein the electrochromic compound is a compound represented by General Formula 1, and an anion of the electrolyte is a monovalent anion having oxidation potential higher than reduction potential of a dication of General Formula 1 by 3.1 V or greater,where X− is a monovalent anion having oxidation potential higher than reduction potential of the dication of General Formula 1 by 3.1 V or greater and W2+ is the dication represented by General Formula 2,
