Abstract: A bearing steel has improved insulation performance by forming a continuous insulating film. The bearing steel includes 0.65 to 1.0 mass % of carbon (C), 1.6 to 2.0 mass % of chromium (Cr), 1.5 to 3.0 mass % of aluminum (Al), 0.8 to 1.2 mass % of manganese (Mn), 0.7 to 1.0 mass % of silicon (Si), 0.1 to 0.3 mass % of nickel (Ni), 0.08 to 0.12 mass % of molybdenum (Mo), and a balance of iron (Fe), in which an oxynitride layer including a nitride layer and an oxide layer is formed on the surface of a material.
