Alumina sintered body, abrasive grain, and grinding wheel
To provide an alumina sintered body, abrasive grains, and a grinding wheel having high hardness and excellent wear resistance. An alumina sintered body comprising: an inner layer comprising alumina crystal grains; and an outer layer covering at least a part of the inner layer from outside, having a higher content of an alkaline earth metal than the inner layer, and comprising alumina crystal grains, wherein the content of the alkaline earth metal in the outer layer is 1.0 to 30.0 mass % in terms of oxide, the alumina sintered body being free from silicon except unavoidable impurities.
