Abstract
A bone substitute material is prepared by firing and pulverizing animal bones into animal bone powder, mixing the animal bone powder and a divalent metal compound into a powdery mixture, and kneading the powdery mixture with chitosan sol. Alternatively, a bone substitute sheet is prepared by mixing at least one of apatite and animal bone powder with chitosan sol into a mixture, forming a pre-processed sheet of the mixture, and neutralizing the sheet by an aqueous solution of a compound. The bone substitute material and sheet have a pH value falling within a neutral range.
