A method for manufacturing an oxidized layer of magnesium-based metal material having excellent corrosion resistance, which is the aspect of the present invention, comprises: a step for preparing a magnesium-based base material; and a step for forming an oxidized layer on the magnesium-based base material by irradiating the magnesium-based base material with plasma which uses source gas. The purpose of the present invention is to environmentally-friendly form the oxidized layer the surface of magnesium and a magnesium alloy by not requiring wastewater treatment.
