The present invention relates to a metal ion recovery device, and an electrode manufacturing method and manufacturing device using the same. The present invention effectively recovers metal ions from a waste etching solution used in etching of an electrode pattern, regenerates the metal ions, and continuously circulates the metal ions to an etching process of a manufacturing process of an electrode for a display for reuse. Therefore, the service life of the etching liquid can be prolonged. 本发明涉及一种金属离子回收装置、利用其的电极制造方法及制造装置，从电极图案的蚀刻中使用的废蚀刻液有效地回收金属离子后进行再生，并连续循环到显示器用电极制造工艺的蚀刻工艺以供再利用，从而可以增加蚀刻液的使用寿命。
