A polisher for polishing a curved surface such as a concave surface of a spectacle lens has a structure in which a polishing pad 3 comprising water passing grooves 5 having a width W of 0.1 to 5 mm is adhered to a dome-shaped elastic base member 2 . The polishing pad 3 is composed of a plurality of pads 31 , and the water passing grooves 5 are formed at the gaps between the pads 31 , whereby the width W of the water passing grooves 5 are made small. It is effective to make the pads 31 polygonal in shape. The polishing pad 3 covers the moving region 6 of the work 8 to be polished. The polishing pad 3 is adhered through a high-tack adhesive layer 4 . A polishing method is adopted in which such a polisher 1 is used and the work 8 is polished by pressing the polishing pad 3 against the work 8 , whereby the polishing pad 3 adhered to the elastic base member 2 can be prevented from being stripped by an end edge of the work 8 , and generation of defective polish can be prevented.
