<P>PROBLEM TO BE SOLVED: To provide a chloride ion removal device which can obtain treated water usable as water for food production and drinking water at a low cost by removing chloride ions (Cl<SP>-</SP>) from water to be treated containing the chloride ions (Cl<SP>-</SP>). Ž<P>SOLUTION: The chloride ion removal device includes an inner tank for storing the water to be treated, an outer tank for storing immersion water for immersing the inner tank, electrodes arranged in the immersion water in the outer tank, and a power source for applying a direct-current voltage to the electrodes. At least a part of the wall or bottom of the inner tank is formed with a microporous film, such as a film made of viscose rayon, which allows penetration of the chloride ions (Cl<SP>-</SP>) but prevents penetration of silver chloride (AgCl), and at least an anode among the electrodes is formed with silver (Ag), whereby the chloride ions (Cl<SP>-</SP>) moved outside the inner tank through the microporous film form silver chloride (AgCl) on the anode and the formed silver chloride (AgCl) precipitates in the immersion water.
