A porous conductor 6a having water permeability is arranged adjacently to the anode 3a and a porous conductor 6b likewise having water permeability is arranged adjacently to the cathode 3b. The porous conductor 6a is formed by packing active carbon being conductive particle into a housing body having water permeability and arranging the active carbon adjacently to the electrode so as to come into contact with the anode 3a. Such porous conductor 6a, etc., have the electrolytic function similar to that of the anode 3a over the entire part and since the active carbon is granular, water can pass through the gaps between the particles of the active carbon.
