There is performed a treatment including a grinding working step of grinding at least a portion of a rolling surface and a sliding surface of a motion guide device using a rolling member by a grinding working using a grinding stone, and a surface treating step of effecting a peening treatment to a friction surface formed by the grinding working to render a defect on the friction surface caused by the grinding working harmless. By manufacturing a motion guide device through such treating steps, a defect such as flaw generated on the friction surface is made harmless, the fatigue strength, sliding performance and lifetime of the device can be improved. Even in a travelling distance test, a travelling distance largely over a calculated lifetime could be achieved. Accordingly, even if a flaw is generated on the friction surface or rolling surface by the grinding working using a grinding stone, the flaw can be made harmless without giving influence to an allowable dimensional accuracy of a member to be treated.
