The electrochromic indicator according to the invention is a multilayer structure and comprises in a sandwich layered arrangement an optically transparent first substrate, an optically transparent first electrode, a layer of a solid inorganic electrochromic material, and a layer of an electrolyte. Interposed between the electrolyte layer and a second electrode is a layer which is a film of an oxidation-reduction polymer, or a filled polymer film, or a paste containing an oxidized form (Ox) and a reduced form (Red) of compounds which produce on the second electrode a reversible oxidation-reduction reaction of the following type: Red�
