摘要： An inspection method of a rolling element (91) includes the steps of: projecting an X-ray (99) from a light source (12) to a rolling element (91), detecting the X-ray (99) passing through the rolling element (91) by a detector (13), calculating data of the detected X-ray (99) to form an image, and detecting a defect in the rolling element (91) based on the image. At the step of projecting an X-ray (99), the light source (12) rotates relatively around the rolling element (91) while the X-ray (99) is projected to an entire region of the rolling element (91) facing the light source (12). At the step of forming an image, data of the X-ray (99) for one circuit around the rolling element (91) is calculated to generate the image.
