PROBLEM TO BE SOLVED: To provide an electric deionization apparatus which has simple structure and can be easily manufactured. SOLUTION: A cation exchange membrane 3 and an anion exchange membrane 4 are arranged between a cathode 1 and an anode 2. A concentrating chamber and cathode chamber 5 is formed between the cathode 1 and the cation exchange membrane 3. A concentrating chamber and anode chamber 6 is formed between the anode 2 and the anion exchange membrane 4. A desalting chamber 7 is formed between the cation exchange membrane 3 and the anion exchange membrane 4. The concentrating chamber and cathode chamber 5 and the concentrating chamber and anode chamber 6 are respectively formed of a recess 11 of a plate 10 and of a recess 21 of a plate 20. Mesh-shaped membrane electrodes 1, 2 are respectively formed by sputtering or the like at bottom surfaces of the recesses 11, 21. COPYRIGHT: (C)2004,JPO
