A bone repair materials being superior in apatite-firming ability and its stability in a storage and high in scratch resistance is disclosed. The material is produced by a method comprising the steps of: immersing a substrate made of titanium or a titanium alloy in a first aqueous solution that does not contain calcium ions but contains at least one cation selected from the group consisting of sodium ions and potassium ions and is alkaline； immersing the substrate in a second aqueous solution that does not contain phosphate ions but contains calcium ions； heating the substrate in a dry atmosphere； and treating the substrate with hot water of 60°C or higher or with steam.
