In an angular ball bearing (), an outer race () has at least one diameter-directional hole () that supplies lubricating oil and passes through from the outer circumferential surface to the inner circumferential surface along the diameter direction. In a cross-section taken along the axial direction passing through a center (O) of the ball (), the axial-directional position of a line extending through a central axis (X) of the diameter-directional hole () in the outer circumferential surface of a retainer () is located between an intersection position (A), at which an outer circumferential surface () of the retainer () and a surface of a ball () intersect, and an axial-directional end (B) of a pocket (P).
