PROBLEM TO BE SOLVED: To provide both an electric type device for producing deionized water, in which treated water having excellent water quality can be stably produced even in such operation that pressure difference is caused in a desalination chamber and a concentration chamber, and a deionization module used therefor. SOLUTION: The deionization module 10 for the electric type device for producing deionized water is laminated with a cation exchange membrane 1, a cell frame 3 and an anion exchange membrane 2, and an ion exchanger is packed in the inside. In the cation exchange membrane 1 and the anion exchange membrane 2 of the deionization module, a supporting cloth 9 is used as a base material or a supporting material 9 is used as a base material or a supporting material and also, in an assembly state, both the fiber direction 11 of the supporting cloth 9 and the direction of an edge 11a in the inside of the cell frame 3 are in the mutually different directions.
