Provided are an electrowinning system wherein the accumulation of a side reaction product on an anode and the increase of electrolytic voltage caused thereby can be suppressed, and an electrowinning method using the system. Specifically provided is an electrowinning system for depositing a desired metal on a cathode by passing a predetermined electrolytic current between an anode and the cathode which are disposed in an electrolyte. Said system is characterized in that the electrolyte is a sulfuric acid-based or chloride-based solution containing ions of the desired metal, and the anode is configured by forming a catalytic layer containing amorphous iridium oxide or amorphous ruthenium oxide on a conductive base. |
