A hot-dipped galvanized steel sheet containing high manganese which has superior processability and intensity and a manufacturing method thereof are provided to increase yield strength by optimizing the amount of the addition of silicon, niobium, and vanadium. A hot-dipped galvanized steel sheet containing high manganese which has superior processability and intensity includes carbon of 0.4~0.8wt%, manganese of 10~30wt%, aluminum of 1.0~2.0wt%, niobium of 0.01~0.1wt%, vanadium of 0.01~0.2wt%, remnants Fe, and impurities etc. The surface of the high manganese steel sheet includes a plating layer made of Fe of 2~6wt%, Mn of 2~8wt% and remnant Zn. |
