摘要:
PROBLEM TO BE SOLVED: To provide a polishing composition which can effectively reduce the number of minute particles remaining on a surface of a polishing object after being polished.SOLUTION: There is provided the polishing composition which contains abrasive grains, water-soluble polymers, and water. A weight-average molecular weight of the water-soluble polymers is equal to 20×10or less. In the polishing composition, a ratio (D95/D50) of a 95% cumulative diameter D95 to a 50% cumulative diameter D50 is equal to 2.00 or less, in a volume-based particle diameter distribution for grains in the polishing composition that is measured by applying dynamic light scattering using a concentration at which a content of the abrasive grains is 0.2 mass%.
