Abstract
An electrochromic apparatus includes an electrochromic element comprising a pair of electrodes and an electrochromic layer disposed between the pair of electrodes; and drive circuits connected to the electrochromic element, the drive circuits including a drive circuit A and a drive circuit B, in which, when no voltage is applied in a pulse width modulation (PWM) drive of the drive circuit A, a resistance value of the drive circuit A is larger than a resistance value of the electrochromic element, and in which when no voltage is applied in a PWM drive of the drive circuit B, the pair of electrodes is short-circuited.
