The present invention relates to a method for manufacturing a lithium electrode. More particularly, in the manufacture of a lithium electrode, a protective layer capable of protecting a lithium metal is firstly formed on a substrate surface-treated by a plasma and a corona process, a lithium metal is deposited on the protective layer, and then the deposited lithium metal layer is transferred to a current collector. Therefore, the method enables manufacture of a thin lithium electrode having a uniform thickness, and can improve the energy density of a lithium secondary battery using the lithium electrode manufactured as described above.
