Abstract: An electrochromic device according to the present disclosure includes an electrochromic element that includes a first electrode, a second electrode, and an electrochromic layer disposed between the first electrode and the second electrode. The electrochromic layer contains an anodic electrochromic compound and an oxidizable substance. The oxidizable substance is a substance which substantially does not undergo a color change due to oxidation and whose oxidant is not reduced. An oxidation reaction of the oxidizable substance is less likely to occur than an oxidation reaction of the anodic electrochromic compound. A controller is configured to control oxidation of the oxidizable substance based on a charge balance of the electrochromic element.
