Polishing method and polishing pad

A polishing method comprising:

• providing a disc-shaped polishing pad, wherein:
• the polishing pad has a peripheral surface on a polishing surface side in an axial direction of a disc of an arc surface;
• and
• the polishing pad has a hardness of 40 or more, determined according to Annex 2 of JIS K7312:
• 1996, “Spring Hardness Test Type C Testing Method”;
• supplying a slurry containing abrasives to a polished surface larger than the polishing surface;
• and
• pressing the polishing surface against the polished surface and moving the polishing pad to polish the polished surface,
• wherein the polished surface is a concave curved surface that is a coated film surface of part of a vehicle, a railway vehicle, an aircraft, a bicycle, or a ship.

A polishing method comprising:

• supplying a slurry containing abrasives to a polished surface;
• providing a polishing pad in which having a hardness of 40 or more and 80 or less, determined according to Annex 2 of JIS K7312:
• 1996 “Spring Hardness Test Type C Testing Method”;
• and
• pressing a polishing surface of the polishing pad against the polished surface and moving the polishing pad to polish the polished surface,
• wherein a support layer softer than the polishing pad is fixed to a surface on a side opposite to the polishing surface of the polishing pad, and the support layer has a thickness of 2.0 mm or more and 50 mm or less;
• and
• wherein the polished surface is a concave curved surface that is a coated film surface of part of a vehicle, a railway vehicle, an aircraft, a bicycle, or a ship.
