PROBLEM TO BE SOLVED: To provide an electrochromic element which has no coloring and is simply realized with excellent reproducibility. SOLUTION: 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 WO<SB>3</SB>and TiO<SB>2</SB>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. COPYRIGHT: (C)2005,JPO&NCIPI
