Provided is an anode for electrowinning such that, in electrowinning using a sulfuric acid-based electrolyte solution, the electric potential for oxygen generation is lower than for a lead electrode, lead alloy electrode, and coated titanium electrode, the electrolysis voltage for electrowinning can be reduced, and the basic units for electric energy can be reduced for a desired metal. This anode can be used as the anode for electrowinning of various types of metal and has superior mass producibility. The anode for electrowinning is used in the electrowinning that uses a sulfuric acid-based electrolyte solution, and a catalyst layer that includes noncrystalline ruthenium oxide and noncrystalline tantalum oxide is formed on a conductive base substance. |
