PURPOSE:To obtain the titled element having an excellent stability by using a high polymer composite film obtd. by polymerizing a monomer capable of forming a conductive high polymer with a polymerization, in a porous high polymer film. CONSTITUTION:The polymerization is carried out by using the porous high polymer film made of an ethylene-2-methylpenten copolymer as a diaphragm 2, and by feeding a chloroform solution saturated with an anhydrous ferric chloride into a cell 1 for the solution of an oxidizing reagent, and introducing slowly a nitrogen gas saturated with thiophene to the cell 3 for a gaseous monomer. And then, the film 2 is take out and washed with an ethanol and an ammoniacal ethanol solution in order. The composite film is deposited with gold on a side of the cell contacting with an oxidizing reagent, and then is dipped with an acetonitrile solution of lithium perchlorate followed by taking it out. The cell of the electrochromic element is assembled using a counter electrode composed of 'NESA(R)' glass.
