Provided is an electrodeionization device that has improved boron removing performance compared to conventional high-performance electrodeionization devices. This electrodeionization device includes: a negative electrode and a positive electrode; and a concentration chamber and a desalination chamber alternately formed by arranging a plurality of cation exchange membranes and anion exchange membranes between the negative electrode and the positive electrode. The desalination chamber is filled with an ion exchange resin. The ion exchange resin has an average particle size of 100-300 μm. The uniformity coefficient of said ion exchange resin is preferably 1.1 or less. |
