[Challenge] trace amounts of Ca, a non-purified water and raw water containing an alkaline earth metal ions, such as Mg, in the electrolytic apparatus of the supply structure of the raw material water to the cathode chamber, to the cathode surface, which is provided to the cathode chamber providing an electrolytic apparatus which can prevent the scale of the deposition of an alkaline earth metal.
A cation exchange consisting film solid polymer electrolyte diaphragm 3 more film forming an anode 4 and a cathode 5 which are adhered respectively to both sides - to press the electrode assembly 2 from both sides, a solid polymer electrolyte diaphragm 3 , consists of an electrolytic cell 1 was molded to close contact with the anode 4 and the cathode 5 has a flexibility as a cathode 5, a porous conductive material having a large number of fine voids therein, the cathode 5 inside a fine into the gap, stores the scale composed mainly of alkaline earth metals, the cathode 4 and the solid polymer electrolyte diaphragm 3 contact interface to alkaline earth metal is prevented from being concentrated precipitated electrolysis equipment and electrolytic ozone water production apparatus.
