Provided are a high-strength bead wire and a method of manufacturing the same. The method includes preparing a wire rod containing 0.86% to 1.02% by weight of carbon, applying 5 g/m2 to 10 g/m2 of phosphate coating onto the surface of the wire rod, and drawing the wire rod onto which the phosphate coating is applied. In the drawing, the wire rod is drawn by a drawing apparatus including a drawing die capable of drawing the wire rod and a pressure die installed in front of the drawing die and capable of applying pressure to the wire rod. The diameter of the pressure die is 1.05 times to 1.20 times the diameter of the drawing die. The high-strength bead wire includes a wire rod containing 0.86% to 1.02% by weight of carbon and 5 g/m2 to 10 g/m2 of the phosphate coating applied onto the surface of the wire rod and is manufactured by the above-described method.
