PROBLEM TO BE SOLVED: To provide a roller bearing optimum for use in an misalignment condition. SOLUTION: In this roller bearing forming crowning on a raceway surface of a bearing bearing ring or a rolling face of a roller, a profile line of negative side crowning 13b formed toward a negative side in the direction of generating line is a curve expressed by an expression (I), and a profile line of positive side crowning formed toward a positive side in the direction of generating line is a curve expressed by an expression (II). When optimizing design parameters K1n, K2n, zmn and K1p, K2p, zmp in the expressions (I) and (II) by taking misalignment into account, at least one of K1n≠K1p, K2nan≠K2pap, and zmn≠zmp is satisfied.
