摘要
The object of the present invention is to provide a sliding member, a prosthesis and a method of producing the sliding member, which can suppress production of abrasive wear debris by suppressing friction of the sliding section, and also can maintain satisfactory mechanical characteristics in vivo. A sliding member comprising: a substrate 1 capable of forming hydroxyl groups; and a biocompatible material layer 4 laminated on appropriate sections of the substrate 1, wherein hydroxyl groups are formed on at least a required section of a surface of the substrate 1 by surface treating to form a surface-treated layer 2, while the biocompatible material layer 4 is formed from a polymer containing phosphorylcholine groups, and wherein the substrate 1 and the biocompatible material layer 4 are joined via a binder layer 3 formed from silica being covalently bonded with the hydroxyl groups and the biocompatible material, respectively.
