PROBLEM TO BE SOLVED: To provide an angular ball bearing which is made lightweight by reducing the axial dimension of an outer ring and/or an inner ring, and which is prevented from decreasing in removability from the stacked state of an outer-ring assembly and an inner-ring assembly. SOLUTION: The upper surface of the outer ring 2 is positioned axially inward of the end face of the large-diameter annular part 8 of a cage 5 and the outside diameter of the large-diameter annular part 8 side end face of the cage 5 is larger than the inside diameter of the lower surface of the outer ring 2. Chamfered parts 8b, 2d for providing ease of removal from the stacked state of the outer-ring assemblies 6A, 6B are provided, respectively, on the large-diameter annular part 8 side end face of the cage 5 and the lower surface of the outer ring 2.
