PROBLEM TO BE SOLVED: To provide a member appropriate for a sliding part of an artificial joint by strongly bonding a high-strength metal substrate and a dense and high-hardness surface layer formed on the surface of the metal substrate.SOLUTION: In a method for producing an artificial joint member, the metal substrate is prepared, powder containing one or more components selected from aluminum and zirconium is cold-sprayed on the surface of the metal substrate to coat the surface, and at least a part of the coated part is oxidized after the surface is heated in vacuum or within an inert gas.
