Abstract: An electrochromic device includes: a first electrode which transmits light; a second electrode disposed opposite the first electrode; an electrolyte located between the first electrode and the second electrode, and containing metal depositable on one of the first electrode and the second electrode, according to a potential difference between the first electrode and the second electrode; a driver which applies a predetermined potential to a target electrode which is at least one of the first electrode and the second electrode; and a controller which changes a potential application portion of the target electrode to which the predetermined potential is applied, in a potential application period during which the predetermined potential is applied.

Abstract: An electrochromic element includes: a first electrode which transmits light; a second electrode disposed opposite the first electrode; and an electrolyte containing metal and located between the first electrode and the second electrode. The metal is depositable on one of the first electrode and the second electrode, according to a voltage applied between the first electrode and the second electrode, and a second deposition voltage at which deposition of the metal on the second electrode starts is higher than a first deposition voltage at which deposition of the metal on the first electrode starts.
