Abstract
Deterioration of characteristics due to repeated cycles of coloration and discoloration in an electrochromic element comprising an oxidative coloration layer composed of a nickel oxide and a electrolyte composed of a solid electrolyte is suppressed. A lower ITO transparent electrode filmis formed on a transparent substrate. A nickel oxide filmmaking up an oxidative coloration layer, an intermediate layer, a tantalum oxide film making up a solid electrolyte layer, a mixed film comprising a tungsten oxide and a titanium oxide making up a reductive coloration layer, and an upper ITO transparent electrode filmmaking up an upper electrode film are formed on the lower ITO transparent electrode filmon this order. The intermediate layeris a transparent film comprising a metal oxide such as SnO, a metal such as Al, or a composite of the metal oxide and the metal.
