Abstract
There is disclosed an electrochromic element in which an oxidative color-forming layer is composed of an organic material and a reductive color-forming layer is composed of an inorganic material. The electrochromic element comprises a pair of electrodes, at least one of which is transparent, the oxidative color-forming layer composed of organic materials such as polyaniline, polypyrrole, polythiophene, etc. and the reductive color-forming layer composed of inorganic materials such as WO.sub.3, MoO.sub.3, TiO.sub.2, etc. formed between the pair of electrodes to face to each other, and an electrolytic solution or a solid or semi-solid electrolyte layer sealed between the both color-forming layers.
