Abstract
There is provided an electrochromic device comprising a pair of transparent substrates facing each other, a pair of transparent electrodes facing each other between the pair of transparent substrates, and an electrochromic layer and a transparent ion conductive layer sandwiched by the pair of transparent electrodes, wherein at least the electrochromic layer and the transparent ion conductive layer are coated with a resin in a state that carrier precursor in the electrochromic layer and in the transparent ion conductive layer is ionized. As a result, film breakage of the electrochromic device and peeling off of the sealing resin and the sealing substrate are prevented, thus improving the durability of the electrochromic device.
