Abstract
The present invention provides an abrasive pad for abrading a surface to be abraded in the presence of an abrasive solution, which includes a hydrophobic polymer as a base material, and in which a graft-polymer chain having a hydrophilic group is introduced into the surface of the hydrophobic polymer. The hydrophilic group possessed by the graft-polymer chain is preferably a nonionic hydrophilic group selected from the group consisting of hydrophilic groups having an N-monoalkyl substituted structure and hydrophilic groups having an N-dialkyl substituted amide group. An amount of the hydrophilic graft-polymer to be introduced into the base material is preferably 10.0% to 150.0% in terms of graft ratio.
