PROBLEM TO BE SOLVED: To provide a device for supplying a copper ion to water capable of effective copper ion elution, which can take place quantitatively from the theoretically set value of the current obtained by the amount of water flow per unit and the desired concentration of the copper ion. SOLUTION: The device for supplying the copper ions to the water includes a group of electrodes comprising a plurality of pairs of the copper electrodes which are disposed evenly spaced and parallel to one another and a power source applying a DC voltage to each of the pairs of the electrodes. The device keeps the group of the electrodes inserted in a water conduit having a square or rectangular cross section so that the copper electrodes are disposed parallel with the water flow direction and the edge of the electrode parallel with the water flow direction is in absolute contact with the wall of the conduit.
