したものが一般に広く使用されている。2. Description of the Related Art Copper refining by an electrolytic method is widely used. In this method, an anode is usually made of impure copper, and pure copper is electrodeposited on the surface of a cathode plate immersed in an electrolytic cell. As the cathode plate, there is a part using a titanium plate, but since the metal itself is expensive and the workability is difficult, there is a drawback that it becomes expensive, and the suspension bar made of copper is used. A stainless steel plate screwed to the bottom is generally widely used.

カソードプレートを提供することを目的とする。However, in the cathode plate for copper refining using the stainless steel plate of the conventional example, since the stainless steel plate to be the electrode is fixed by screwing, contact resistance is generated at that portion. There was a problem that the electrical conductivity was poor. Therefore, it is theoretically possible to directly weld a stainless steel plate to a copper rod, but copper and stainless steel are not very familiar and the weldability is poor. There was a problem that the sex deteriorates. In addition, the suspension rod made of copper is gradually corroded by the electrolytic solution, resulting in a short service life. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cathode plate for copper refining, which has good electric conductivity, long life, and low cost.
