Abstract:
An apparatus for polishing a workpiece, comprising:a press member which is pressed, while the workpiece is rotated, against a back surface of a polishing tape to press the polishing tape against a target surface of the workpiece, wherein each portion of a press surface of the press member that presses the back surface of the polishing tape is located on a parallel plane which is parallel to a contact plane that contacts the target surface of the workpiece and which is distant from the contact plane by a thickness of the polishing tape on one of opposite sides of the contact plane that is opposite to the other side thereof on which the workpiece is located, or located on one of opposite sides of the parallel plane that is opposite to the other side thereof on which the workpiece is located; and a holding portion which holds the press member, wherein the holding portion includes a first device which holds the press member such that the press member is rollable about a rolling axis line which crosses a rotation axis line about which the workpiece is rotated and the holding portion further including a second holding device which holds the press member such that the press member is movable relative to the holding portion along a movement axis line which crosses the rotation axis line of the workpiece.
