and photographs the inspection surface with a camera. The illumination device isarranged so that at least a part of the illumination device is present in a space
surrounded by the inner peripheral surface of the rolling bearing. The camera is arrangedat a position where an angle formed between a straight line connecting a position closestto the camera on the inspection surface to the camera and a line perpendicular to theinspection surface at that position is larger than an incident angle of the diffused light atthe position closest to the camera.
