The electrochromic elementincludes a plurality of anode terminals (A, A) electrically connected to the anode electrode, and a plurality of cathode terminals (C, C) electrically connected to the cathode electrode, and each of the anode terminals constitutes a terminal pair in combination with one of the cathode terminals. At least part of a first application period in which the drive meansapplies a voltage to a first terminal pair that is one of the terminal pairs and at least part of a second application period in which the drive meansapplies a voltage to a second terminal pair that is another one of the terminal pairs are not overlapped with each other.
