Abstract

Provided is a polishing composition containing abrasive grains, an acid, an oxidant, and a defect inhibitor. The defect inhibitor is a compound having a guanidine skeleton. The polishing composition is used in polishing a nickel-phosphorus plated substrate for a magnetic disk. The compound having a guanidine skeleton is preferably guanidine phosphate.
