PROBLEM TO BE SOLVED: To provide an electric deionizing apparatus enabling an increase in treatment flow rate and the reduction of manufacturing cost and capable of being also constituted so as to enhance durability. SOLUTION: A frame 20 has a rectangular shape, and a first desalting chamber 21 and a second desalting chamber 22 are formed on one half side and other half side in the long side direction of the frame. Introducing ports 31 and 32 of water to be treated are respectively arranged to the upper part of the desalting chamber 21 and the upper part of the desalting chamber 22 and outflow ports 41 and 42 of desalted water prepared by desalting water to be treated are respectively provided to the lower part of the desalting chamber 21 and the upper part of the desalting chamber 22. Openings 51 and 52 for forming water channels for guiding concentrated water to respective concentration chambers are provided to the upper part of the desalting chamber 21 and the lower part of the desalting chamber 22. An opening 53 for forming a water channel for taking out concentrated water from the respective concentration chambers is provided to a crossbeam part 54. A large number of the cation exchange membranes, the frames for forming the desalting chambers, anion exchange membranes and frames for forming the concentration chambers are laminated in this order.
