ABSTRACT:
A chemical mechanical polishing aqueous dispersion comprises abrasives (A) containing ceria, an anionic water-soluble polymer (B) and a cationic surfactant (C), wherein the amount of the anionic water-soluble polymer (B) is in the range of 60 to 600 parts by mass based on 100 parts by mass of the abrasives (A) containing ceria, and the amount of the cationic surfactant (C) is in the range of 0.1 to 100 ppm based on the whole amount of the chemical mechanical polishing aqueous dispersion.
