Polishing composition |
| abstract |
A polishing composition used for polishing an object to be polished containing oxygen atoms and silicon atoms, the polishing composition including: abrasive grains A having an average primary particle size of 3 nm or more and 8 nm or less; abrasive grains B having an average primary particle size of more than 8 nm; and a dispersing medium, wherein a content of the abrasive grains B in the polishing composition is larger than a content of the abrasive grains A in the polishing composition, average silanol group density of the abrasive grains A and the abrasive grains B is 2.0 nm−2 or less, and an aspect ratio of the abrasive grains B is more than 1.3 and 2.0 or less. |
