It is an object of the present invention to offer a material suitable for use as a bone substitute, which provides both the fracture toughness of titanium and the bioactivity of apatite, wherein titanium and apatite is tightly adhered, and which is available at low cost. The material is produced by soaking a substrate made of titanium Ti or titanium Ti alloys into alkaline solution, followed by heating of the said substrate to the level of at most the titanium Ti transition temperature.
