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 stackability.
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 lower surface of the outer ring 2 is flush with the end face of the small-diameter annular part 9 of the cage 5 when the rings are stacked. A plurality of projections 12 that abut the lower surface of the cage 5 of an upper outer-ring assembly 6B when outer-ring assemblies 6A, 6B are stacked are provided at predetermined intervals on the end-face-side inner peripheral surface of the large-diameter annular part 8 of the cage 5.
