    Abstract: In the roller bearing, between an outer ring (1) and an inner ring (2), there are interposed a plurality of tapered rollers (3) in a freely rollable manner. A flange portion (4) is formed in the side portion of the inner ring (2). The undercut allowance ratios of a contact ellipse formed due to mutual contact between the flange portion (4) and the end face of the roller (3) is set in the range of −0.6≦(h−b−c)/b≦2, where a grinding undercut dimension on the flange portion (4) is expressed as c, a contact point height between the flange portion (4) and the end face of the roller (3) is expressed as h, and the minor radius of a contact ellipse formed due to contact between the flange portion (4) and the end face of the roller (3) is expressed as b.
