Zusammenfassung:Provided is a block body that makes it possible to quickly produce a dental prosthesis with a good accuracy. A material of the block body including SiO2 in an amount of 60.0 mass % to 80.0 mass %, Li2O in an amount of 10.0 mass % to 20.0 mass %, Al2O3 in an amount of 5.1 mass % to 10.0 mass %, wherein the block body is formed in a column, and a main crystalline phase of the block body is lithium disilicate.
