An electrodeionization apparatus is provided, in which a plurality of cells are formed and arranged in vertical and lateral directions in each desalting compartment whereby various kinds of ion exchangers can be filled so that the arrangement and the mixing rate of the ion exchangers to be filled can be freely selected, and high filling density of the ion exchangers can be achieved. The desalting compartment comprises a rectangular frame 20, a partition member 21, preferably having conductivity, disposed in the frame 20, an ion exchanger 23 filled in cells 22 formed by the partition member 21, an anion-exchange membrane 24 and a cation exchange membrane 25 which are disposed to sandwich the frame 20. The partition member 21 is in a honeycomb form of hexagonal shape such that a pair of sides extend in the longitudinal direction of the frame 20, i.e. in the vertical direction. <IMAGE> |
