A polishing apparatus can effectively prevent abrasive particles from falling off a polishing tape during polishing. The polishing apparatus includes: a polishing head for polishing a peripheral portion of a substrate by pressing a surface of a polishing tape, having abrasive particles fixed on the surface, against the peripheral portion of the substrate while allowing the polishing tape to travel in one direction; and a conditioning apparatus, disposed upstream of the polishing head in the traveling direction of the polishing tape, for conditioning the surface of the polishing tape in advance in order to prevent the abrasive particles from falling off the surface of the polishing tape during polishing.
