A guide includes a brittle material layer and a magnetically attracting magnetic body, e.g., a metal layer. A recess and a projection are formed on the metal layer. The brittle material layer is made of, e.g., a sprayed ceramic material and covers the recess formed on the magnetically attracting metal layer. A movable body moves as it levitates above the surface of the brittle material layer.
