PROBLEM TO BE SOLVED: To provide a porous ion exchanger having a specific open-cell structure and a remarkably large pore volume and specific surface area, a deionization module having a simple structure which is easy to assemble, and a power-saving type. To provide an electric deionized water production device. SOLUTION: The interconnected macropores have an open cell structure having mesopores having an average diameter of 1 to 1000 µm in the walls of the macropores, and have a total pore volume of 1 to 50 ml / g. And a deionization module in which the ion exchange groups are uniformly distributed and the ion exchange capacity is 0.5 mg equivalent / g or more, and a porous ion exchanger having a dry porous body or more is filled between both ion exchange membranes. A power-saving type electric deionized water production device equipped with this. |
