Abstract
An electrochromic apparatus comprises an electrochromic device and a drive unit operating for normal drive and heating drive of the electrochromic device. The electrochromic device comprises a pair of electrodes and an electrochromic layer including at least an electrochromic material and a solvent. Each of the paired electrodes has at least a pair of power supply sections on a surface thereof. The pair of power supply sections include a first power supply section and a second power supply section arranged oppositely relative to the first power supply section on the surface. The drive unit operates for the heating drive such that the electrochromic layer is heated by applying an alternating voltage between the pair of power supply sections of each of the paired electrodes so as to put any oppositely disposed positions of the paired electrodes in phase with each other.
