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.
