The present invention relates to a lithium electrode for a lithium battery and a manufacturing method thereof and, in particular, to a lithium electrode for a lithium battery using a solid high-ionic conductor having a three-dimensional porous structure and a manufacturing method thereof. That is to say, the present invention provides a lithium electrode for a lithium battery and a manufacturing method thereof capable of improving a cycle lifetime and a high-rate capability by securing an ion conduction path in the lithium electrode and by improving electrochemical reactivity in the process of charging and discharging electricity, wherein lithium or lithium alloy is filled into each pore and dispersed by applying the solid high-ionic conductor having a three-dimensional porous for securing the ion conduction path in the lithium electrode for a lithium battery using a solid high-ionic conductor instead of an existing liquid electrolyte. [Reference numerals] (AA) Manufacture a solid high-ionic conductor having a three-dimensional porous structure;(BB) Fill lithium metal in each pore;(CC) Joint a porous structure filled with lithium with an electricity collecting copper body
