To provide an electrochromic element which has no coloring and is simply realized with excellent reproducibility.

The electrochromic element comprises a transparent conductive film 2, an oxidation coloring layer, an electrolyte layer 5, a reduction coloring layer and a transparent conductive film 10 sequentially constructed on a substrate 1. The reduction coloring layer is constructed with a multilayer films 3, 4 of WO3 and TiO2 and the oxidation coloring layer is constructed with a multilayer films 6, 7 of Ir oxide and Ni oxide. The multilayer films 3, 4, 6, 7 are deposited with vacuum deposition, ion plating, ion assisted deposition and sputtering method.
