Provided is bearing steel having excellent fatigue life by minimizing segregation during casting of the bearing steel and reducing the generation of large carbides in a segregation band. According to the present invention, high-carbon chromium bearing steel including 0.5 wt% to 1.2 wt% of carbon (C), 0.15 wt% to 2.0 wt% of silicon (Si), 0.05 wt% to 0.45 wt% of manganese (Mn), 0.025 wt% or less (excluding 0 wt%) of phosphorus (P), 0.025 wt% or less (excluding 0 wt%) of sulfur (S), 0.1 wt% to 1.6 wt% of chromium (Cr), 0.01 wt% to 0.3 wt% of Ce, and iron (Fe) as well as other unavoidable impurities as a remainder and a method of manufacturing the same are provided. |
