A cation exchange membrane (11) and an anion exchange membrane (12) are alternately arranged between an anode (20) and a cathode (19). A desalination chamber (14) and a concentrating chamber (15) are alternately formed between both the exchange membranes (11), (12). Then, the desalination chamber (14) is formed to hold a channel through which liquid flows from one to the other side of the desalination chamber, and allow the cation exchange membrane (11) to contact the anion exchange membrane (12). There is thus obtained an electrodeionization water producing apparatus which maintains a deionizing efficiency as in a conventional case, has a simple structure, is easy to manufacture, and has a high degree of freedom of apparatus configuration.
