Beschreibung
Zusammenfassung:	An electrochromic element (100) including: first electrode (101); second electrode (102) disposed to face the first electrode (101) with a gap between the first electrode (101) and the second electrode (102); first electrochromic layer (104) disposed on or above the first electrode (101), including conductor or semiconductor nano-structures and an electrochromic compound; and electrolyte layer (103) including an electrolyte, disposed between the first electrochromic layer (104) and the second electrode (102), 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 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,
