PROBLEM TO BE SOLVED: To increase a decomposition rate by making the distance between an anode and a cathode constant with a relatively simple structure. SOLUTION: The electrochemical cell has a perforated partition wall 16 of a blind cylindrical form which partitions a liquid vessel 11 in such a manner that an cathode chamber 19 in which an anolyte 17 is stored is formed on the inner side and a cathode chamber 20 in which a catholyte 18 is stored is formed on the outer side, respectively, the cylindrical anode 12 which is disposed within the cathode chamber and allows the flow of the anolyte, the cylindrical cathode 13 which is disposed in the cathode chamber so as to enclose the anode via the partition wall, and a circulating means 21 which circulates the anolyte solusion as to pass the anode. The cell is provided with a supply section 22 for supplying the material to be treated. The circulating means 21 has an electric motor 21a, a revolving shaft 21b which is disposed in a perpendicular direction at the center of the partition wall 16, has the bottom end arriving at the bottom of the partition wall 16 and is connected at its top end to a motor shaft of the electric motor 21a, and rotary vanes 21c which are fixed to the revolving shaft 21b and circulating the anolyte 17 and the material to be treated so as to be passed through the anode 12 and to be returned into the anode 12 by centrifugal force.
