PROBLEM TO BE SOLVED: To provide a polishing tool capable of further enhancing magnetic flux density in the vicinity of an end of the polishing tool.SOLUTION: The polishing tool for performing surface treatment by magnetic action includes a tip magnet 12 attached to an end of a support 11, and a rear magnet 14 comprising a ring-shaped magnet disposed in the rear of the tip magnet. An outer diameter of the rear magnet is larger than that of the tip magnet. Magnetic poles of the tip magnet are designed the same as those of an end face of the rear magnet closer to the tip magnet. |
