ABSTRACT:
Abrasive grains have mainly grains with a roundness of 0.50 or more and 0.75 or less, where the roundness is defined as the ratio of the circumference of a circle having the same area as that of a grain to the perimeter of that grain. An abrasive has the abrasive grains and at least one of an oxidizer, an oxide solution, an abrasive grain dispersion agent and a basic compound. An abrasive solution has the abrasive grains and water or hydrophilic substance.
