An improved implant comprising a metallic base material and a coating layer of a ceramics which is formed by thermally sprayed firstly a bonding agent and secondly ceramic powders (optionally containing a porcelain) around the outersurface of the metallic base material. The implant has a sufficient mechanical strength (e.g. impact strength) and hence an excellent break-resistance and further a good affinity to tissues of living bodies and is useful for implantation in various bones including tooth roots and joints in living bodies.
