The CDI type filter according to the present invention relates to a CDI type filter having a case portion for purifying raw water in a CDI method through an electrode portion formed by alternately stacking electrodes and separators, and including the electrode portion. The portion is formed to be longer in the length direction than the width direction, and is formed in the width direction at predetermined intervals in the length direction to have a through hole penetrating the electrode portion in the thickness direction, and the electrode portion is defined in the longitudinal direction with the through hole as a boundary. Accordingly, it is divided into a plurality of electrode units, and each of the electrode units has an outlet hole penetrating the electrode unit in a thickness direction in a central portion, and the case portion has an inlet through which raw water is obtained, and in each of the outlet holes It is characterized in that it has a corresponding outlet, and the raw water flowing into the electrode unit through the through hole is purified and then discharged to the outlet through the outlet hole.
