PROBLEM TO BE SOLVED: To provide a roller bearing for supporting a camshaft or the like of an engine for an automobile in which rollers can revolve smoothly. SOLUTION: The roller bearing comprises an outer ring formed by continuously connecting circular arc-shaped outer ring members in the circumference and the rollers arranged along the inner diameter surface of the outer ring. A slope surface 22i is formed at either or both of circumferential ends of an inner diameter surface of the outer ring member 22a, and a contour line of the slope surface 22i is directed orthogonally to the revolution direction of the rollers.
