Compound electrode for electrolysis
 An electrolytic composite electrode provided with a cathode formed from a drum to be rotated and an anode having a circular-arc inner surface facing the cathode at a certain interval and capable of keeping an electrolytic solution between the anode and the cathode. The anode comprises a first electrode substrate at least whose portion contacting the electrolytic solution is made of a corrosion-resistant metal and which has a plurality of female screw portions provided along a line parallel with the rotation axis of the drum, a second electrode substrate whose one side is covered with an electrode catalyst and which is formed with a titanium tie plate divided on a plurality of parting faces parallel with the rotation axis of the drum and has a plurality of holes formed on the center axis parallel with the parting faces, a bolt screwed to the female screw portion of the first electrode substrate to secure the second electrode substrate to the first electrode substrate, a first intermediate member provided for the circumferential portion of the bolt between the first electrode substrate and the second electrode substrate, and a second intermediate member provided for the vicinity of the circumference of the second electrode substrate between the first electrode substrate and the second electrode substrate.
