A cage for an angular ball bearing including relatively rotatably opposed outer and inner rings (20, 30) and multiple balls rollably interposed between the rings, the cage holding the balls at specific intervals in the circumferential direction, comprising: a large-diameter side circular part and a small-diameter side circular part arranged side by side in the axial direction; and multiple pockets each configured to hold one of the multiple balls between the large-diameter side circular part and small-diameter side circular part, characterised in that: each of the pockets includes: a cylindrical hole opened in the radial outer peripheral surface of the cage and having an inside diameter set constant over a specific distance from the cage radial outer peripheral surface; and a conical hole opened in the radial inner peripheral surface of the cage and having an inside diameter reducing continuously from the diameter-direction inside end of the cylindrical hole toward the cage radial inner peripheral surface; where the inside diameter of the conical hole in the cage radial inner peripheral surface is expressed as A and the diameter of the ball is expressed as Dw, A/Dw≤0.94; where the specific distance of the cylindrical hole is expressed as C and the inside diameter of the cylindrical hole is expressed as B, C/B≤0.35; and the minimum value D of the difference between PCD of the ball and the outside diameter of the cage radial outer peripheral surface and the diameter Dw of the ball satisfy the relational expression, D/Dw≥0.04. a large-diameter side circular part and a small-diameter side circular part arranged side by side in the axial direction; and multiple pockets each configured to hold one of the multiple balls between the large-diameter side circular part and small-diameter side circular part, characterised in that: each of the pockets includes: a cylindrical hole opened in the radial outer peripheral surface of the cage and having an inside diameter set constant over a specific distance from the cage radial outer peripheral surface; and a conical hole opened in the radial inner peripheral surface of the cage and having an inside diameter reducing continuously from the diameter-direction inside end of the cylindrical hole toward the cage radial inner peripheral surface; where the inside diameter of the conical hole in the cage radial inner peripheral surface is expressed as A and the diameter of the ball is expressed as Dw, A/Dw≤0.94; where the specific distance of the cylindrical hole is expressed as C and the inside diameter of the cylindrical hole is expressed as B, C/B≤0.35; and the minimum value D of the difference between PCD of the ball and the outside diameter of the cage radial outer peripheral surface and the diameter Dw of the ball satisfy the relational expression, D/Dw≥0.04. each of the pockets includes: a cylindrical hole opened in the radial outer peripheral surface of the cage and having an inside diameter set constant over a specific distance from the cage radial outer peripheral surface; and a conical hole opened in the radial inner peripheral surface of the cage and having an inside diameter reducing continuously from the diameter-direction inside end of the cylindrical hole toward the cage radial inner peripheral surface; where the inside diameter of the conical hole in the cage radial inner peripheral surface is expressed as A and the diameter of the ball is expressed as Dw, A/Dw≤0.94; where the specific distance of the cylindrical hole is expressed as C and the inside diameter of the cylindrical hole is expressed as B, C/B≤0.35; and the minimum value D of the difference between PCD of the ball and the outside diameter of the cage radial outer peripheral surface and the diameter Dw of the ball satisfy the relational expression, D/Dw≥0.04.
