A bearing component having increased rolling-contact fatigue life, the bearing component being made of a bearing steel that satisfies a predetermined chemical composition, and Si (boundary Si), Mn (boundary Mn), Cr (boundary Cr), Cu (boundary Cu), Ni (boundary Ni), and Mo (boundary Mo) included in a matrix phase region (boundary surface region) from the surface of spheroidized cementite to 20 nm away satisfy the formula: 9.0≦1.4×boundary Si+1.8×boundary Mn+5.5×boundary Cu+4.2×boundary Ni+4.8×boundary Cr+5.5×boundary Mo.
