PURPOSE: A method for manufacturing metal plated fiber for shielding electromagnetic waves is provided to improve cohesion between the metal and the fiber by coating metal powder on fiber using electroless plating. CONSTITUTION: The method for manufacturing metal plated fiber for shielding electromagnetic waves comprises the steps of changing the surface of fiber in an amorphous shape by dipping fiber into boiling water for 40 to 120 minutes; etching the surface of the fiber by contacting the surface of the fiber with an aqueous etchant; contacting a catalytic solution onto the etched surface of the fiber; and coating metal powder onto the surface of the fiber by drying the fiber dipped into the metal solution after dipping the catalytic solution adsorbed fiber into an electroless metal solution, wherein the aqueous etchant comprises an acid selected from the group consisting of formic acid, hydrochloric acid, sulfuric acid, chromic acid and a mixture thereof, and a surfactant selected from the group consisting of anionic, cationic and nonionic surfactants and a mixture thereof, and the aqueous etchant comprises 5 to 20 mg/L of stearyl(2-ethoxy)methyl ammonium chloride, 50 to 100 ml/L of formic acid, 5 to 50 ml/L of hydrochloric acid and 0.5 to 7 g/L of trimethylammonium bromide.
