Bearing component and rolling bearing

A bearing component, composed of steel which contains carbon not less than 0.95 mass % and not more than 1.1 mass %, silicon less than 0.3 mass %, manganese less than 0.5 mass %, sulfur less than 0.008 mass %, and chromium not less than 1.4 mass % and less than 1.6 mass % and is composed of remainder iron and an impurity and having a carbonitrided layer formed at a surface portion including a contact surface which is a surface in contact with other components,

• an average concentration of nitrogen in said surface portion being not lower than 0.3 mass % and not higher than 0.6 mass % and variation in nitrogen concentration in said surface portion being not higher than 0.1 mass %,
• an amount of retained austenite in said surface portion being not greater than 8 volume %,
• an area ratio of a precipitate in inside where no said carbonitrided layer is formed being not lower than 11% and
• the surface portion being a region extending from the contact surface to a depth of not more than 20 μm in a direction of thickness of the bearing component.
