A tapered roller bearing (1a, 1b) satisfies the following three conditions: (a1) 0.8≰Hi/Dw≰1.2, (b1) 1.01≰dm/dh≰1.05, and (c1) 2.1≰L/Dw≰3.0, where a pitch circle diameter at a center of a roller length along an axis line (X) of each tapered roller (4) is (dm), the radial dimension of the inner ring (2) at an intersection of the inner ring raceway (2a) and a perpendicular line (v) extending from a position of the pitch circle diameter in a direction perpendicular to the axis line is the thickness (Hi) of the inner ring, a cross-sectional center diameter of the roller bearing is (dh), the length of the tapered roller (4) is the length (L) of the tapered roller, and a half of the sum of the large diameter dimension and the small diameter dimension of the tapered roller (4) is the diameter (Dw) of the tapered roller.
