Abstract
An electrochromic device and a method for manufacturing same, which device has at least a pair of opposed transparent electroconductive layers, a first transparent ion conductive layer provided between the pair of opposed electroconductive layers, a second transparent ion conductive layer adjacent to the first ion conductive layer, a reductive coloring electrochromic layer adjacent to the second ion conductive layer, wherein the first transparent ion conductive layer is formed in an atmosphere containing water vapor and the second transparent ion conductive layer is formed in an atmosphere containing oxygen. Thereby an electrochromic device can be provided, which device exhibits excellent durability when being driven at a high contrast ratio and high resistance to such environments as high temperature and humidity.
