In this conical roller bearing (1a, 1b), when the pitch circle diameter of the center of the length along the axis line (x) of each conical roller (4) is dm, the dimension in the diametral direction of an inner ring (2) at the point of intersection of an inner raceway (2a) and a perpendicular line (v) extending perpendicularly from the axial line (x) from the position of the pitch circle diameter is the inner ring thickness (Hi), the diameter of the center of the cross section of the conical roller bearing is dh, the length of the conical rollers (4) is the conical roller length (L), and 1/2 of the sum of the minor diameter dimension and the major diameter dimension of the conical rollers (4) is the conical roller diameter (Dw), all three conditions are satisfied of: (a1) the ratio (Hi/Dw) of the inner ring thickness (Hi) to the conical roller diameter (Dw) being 0.8 ≤ Hi/Dw ≤ 1.2; (b1) the ratio (dm/dh) of the pitch circle diameter (dm) to the diameter of the center of the cross section of the conical roller bearing (dh) being 1.01 ≤ dm/dh ≤ 1.05; and (c1) the ratio (L/D) of the conical roller length (L) to the conical roller diameter (Dw) being 2.1 ≤ L/Dw ≤3.0.
