Abstract: Disclosed is an ionization water treatment apparatus. The ionization water treatment apparatus includes an electrostatic field generating element generating an electrostatic field, an insulating tube receiving the electrostatic field generating element and blocking temperature transmission between inner and outer parts of the insulating tube, a finishing element preventing water from flowing into the insulating tube, a housing receiving the insulating tube and the finishing element, and a housing connector coupled with the housing at one side of the housing connecting member. The electrostatic field generating element includes a metallic electrode, two carbon electrodes arranged at both sides of the metallic electrode, and a pipe assembling the carbon electrodes with the metallic electrode. The carbon electrode reacts with gas including fluorine (F2) at a predetermined temperature so that a surface of the carbon electrode is treated.
