description	A polishing device includes a substrate holder, a dispenser configured to dispense an abrasive to a surface of a substrate held by the substrate holder, a polisher including an elastic body configured to polish the surface of the substrate as the elastic body is rotated with respect to the surface of the substrate. An area of contact between the elastic body and the surface of the substrate during polishing is smaller than a surface area of a region of the substrate that is to be polished by the elastic body. The elastic body is moved, while the elastic body is rotated, with a downward velocity component prior to contacting the surface of the substrate and with an upward velocity component after the elastic body comes into contact with the surface of the substrate.
