A polishing liquid comprising an abrasive grain, an additive, and water, wherein the abrasive grain includes a hydroxide of a tetravalent metal element, produces absorbance of 1.00 or more and less than 1.50 for light having a wavelength of 400 nm in an aqueous dispersion having a content of the abrasive grain adjusted to 1.0 mass %, and produces absorbance of 0.035 or more for light having a wavelength of 400 nm in a liquid phase obtained when centrifuging an aqueous dispersion having a content of the abrasive grain adjusted to 1.0 mass % for 50 minutes at a centrifugal acceleration of 1.59×105 G. |
