Method for removing ion adsorption device and ionic substance

PROBLEM TO BE SOLVED: To provide a device for removing ionic substance which can exhibit sufficient ion removing power by means of self electric power generation without requiring large equipment, does not cause secondary contamination due to solvent and facilitates the treatment of a material to be adsorbed, and to provide a method of removing ionic substance using the device for removing ionic substance. SOLUTION: The ion adsorption device includes an electrode made of an collector in which a semiconductor photocatalytic film and an electrolyte adsorptive conductive material are tightly adhered to each other.
