There is a dental prosthesis or a component thereof, characterized in that: the dental prosthesis or the component thereof has hydroxyapatite fine particles on a surface of the dental prosthesis or the component thereof； the hydroxyapatite fine particles are sintered bodies； and the hydroxyapatite fine particles have a mean particle size of 10 to 1,000 nm.
