摘要： A polishing method can safely detach and lift up a workpiece from a polishing surface without carrying out the operation of making the workpiece overhang the polishing surface. The polishing method includes carrying out processing of a surface to be polished of a workpiece by supplying a liquid to a polishing surface while pressing the surface to be polished of the workpiece held by a holding device against the polishing surface and moving the workpiece and the polishing surface relative to each other, attracting the workpiece after the processing to the holding device while supplying the liquid to the polishing surface at a decreased flow rate, thereby detaching the workpiece from the polishing surface, and lifting up the holding device together with the workpiece on confirmation of detachment of the workpiece from the polishing surface and attachment of the workpiece to the holding device.
