Abstract

To provide a polishing composition used for polishing of Ni-P substrates to allow effective reduction of the number of nano-defects. Provided is a polishing composition containing silica particles, phosphoric acid, an organic acid, an oxidant, a water-soluble polymer, a nitrogen-containing organic compound, and water. The polishing composition has a pH of 4.0 or lower. Furthermore, provided is a method for polishing a magnetic disk substrate having an electroless nickel-phosphorus plating layer.
