Abstract

An artificial bone which is excellent in the ability to form bone in a living body, reliably thereof, and has high mechanical strength. The process comprises the steps of: mixing granules, composed of a titanium or a titanium alloy powder and an organic binder, with a particulate pore-forming material, pressure-molding the mixture to obtain a molded body, firing the molded body at 1200° C. to obtain a porous body, bringing the porous body into contact with an aqueous alkali solution, subsequently with water of 35° C. or higher for a period longer than that of contacting with the aqueous alkali solution and then heating the porous body at 100 to 650° C., preferably 200 to 600° C.
