Provided are a method for recovering an element and an apparatus for recovering an element, which are capable of recovering elements including a high-purity rare earth element at low cost. The method for recovering an element comprises : a step of preparing a molten salt (2) that contains a rare earth element; and a step of having the rare earth element contained in the molten metal (2) deposit on one of a pair of electrode members (7, 27) by controlling the potentials of the pair of electrode members (7, 27) to predetermined values, while having the molten salt (2) in contact with the pair of electrode members (7, 27). Consequently, an element such as a rare earth element to be recovered can be directly recovered from a molten salt (2) in which the element has been dissolved, and thus the processes in the recovery method can be simplified and the cost can be decreased in comparison to conventional wet separation methods and the like.
