PROBLEM TO BE SOLVED: To provide a surface modification method for a medical device by which a metallic porous thin plate being a medical device surface modification member having excellent connectivity with living tissue is easily joined to the surface of a medical device main body having various surface shapes with high joining strength, consequently the connectivity of the medical device with the living tissue can be substantially improved, and to provide the medical device using the surface modification method for the medical device. SOLUTION: In the surface modification method for the medical device, the metallic porous thin plate 21 is manufactured by molding slurry containing metal powder and a foaming agent into a sheet shape through a foaming process, and then degreasing and sintering a dried molded article, and the metallic porous thin plate 21 is deformed so as to follow the surface shape of at least a part of the medical device body 31 and joined.
