PROBLEM TO BE SOLVED: To provide a polishing device capable of smoothing a surface to be polished provided with various kinds of curvatures such as an aspherical lens with a simple composition. SOLUTION: An abrasive part 2 can be deformed without changing the center position of the abrasive part 2, by supporting the approximate center section of the abrasive part 2 provided with an abrasive surface 2a with a pivot 7 and driving the both end sections in the Z axis direction with a driving means 9. A surface to be polished provided with various kinds of curvatures such as an aspherical lens can be smoothed by performing polishing with the abrasive surface 2a coinceding to the ideal profile and making close contact with the surface to be polished. |
