Abstract:
The present invention relates to a polishing composition containing an abrasive, a water-soluble polymer, an anionic surfactant, a basic compound, and water, in which the anionic surfactant has an oxyalkylene unit, and an average addition mole number of the oxyalkylene unit of the anionic surfactant is more than 3 and 25 or less. According to the present invention, it is possible to provide a polishing composition which can reduce the haze of a polished object and is also excellent in a polishing removal rate.
