Zusammenfassung:	PURPOSE:To improve the close adhesion force of a coating film by physically polishing the surface of a substrate and applying the coating having the fine unevenness, in the application of the hard coat, etc., on the substrate of an optical member made of plastic. CONSTITUTION:As for a surface cleaning/regenerating device for a plastic lens 1, the lens 1 is fixed by a suction member 2, and can be turned around the center line A, and the cylindrical outside surface of a surface polishing member 3 which is formed by shaping the thermal compression polyurethane foam to a hollow cylindrical form is pressed on the surface of the lens 1 by a prescribed load. In the state where the lens 1 and the surface polishing member 3 are in revolution at a prescribed speed, an alumina group polishing liquid is supplied onto the surface polishing member 3 from a liquid discharge nozzle 5, and the surface polishing member 3 is shifted from the center of the lens 1 to the outer peripheral side, and the fine unevenness is formed on the surface of the lens 1. The surface of the lens 1 is coated after such processing.
