PROBLEM TO BE SOLVED: To effectively reduce rotating torque of a tapered roller bearing by restricting vibration of a tapered roller. SOLUTION: In this tapered roller bearing 1, an inner ring raceway surface 11 is formed with a recessed crowning recessed inward in the radial direction, and an outer ring raceway surface 21 is formed with a projecting crowning projecting inward in the radial direction, and a rolling surface 31 is formed with a projecting crowning projecting outward in the radial direction.
