PROBLEM TO BE SOLVED: To prevent a plate material contacting with a polishing brush from moving, resulting in a failure to polish the plate material.SOLUTION: In a polishing method of polishing a plate material with a brush, the plate material is held on a holding surface of a holding base having a protruded part on the holding surface in a vicinity of the protruded part, brush element wires of the brush are abutted on the protruded part from a side of the protruded part, and the brush element wires are bent. The brush element wires bent by the protruded part are moved from the protruded part onto the plate material, and are abutted on a surface of the plate material. The plate material is polished by the brush by sliding the brush with respect to the plate material while the bent brush element wires abut on the surface of the plate material.SELECTED DRAWING: Figure 3 |
