Abstract
An object of the present invention is to provide a means capable of decreasing micro-scratches of a polishing target after polishing. An abrasive grain dispersion according to the present invention is an abrasive grain dispersion containing abrasive grains having an average primary particle size measured by a BET method in a range of 1 nm or more to 50 nm or less and a dispersing medium, and having a pH value of 7 or more to 12 or less, wherein when a content of the abrasive grains is converted to 30 mass% with respect to a total mass of the abrasive grain dispersion, the number of abrasive grains having a particle size in a range of 0.2 ?m or more to less than 0.3 ?m, measured by a number counting type particle size distribution meter, is equal to or less than 25,000,000 grains/cm3.
