1. A medical device comprising:
a main body that is an artificial prosthetic member; a metallic porous thin plate deformed to follow at least a part of a surface shape of the main body and joined thereto, wherein, the metallic porous thin plate is prepared by: molding a slurry containing a metal powder, a foaming agent, a water-soluble resin binder, and water into a sheet shape; subjecting the slurry to a foaming process; drying the slurry; and defatting and sintering the resulting compact, an average grain diameter of the metal powder is in the range of 0.5 to 50 μm, a content of the metal powder in the slurry is in the range of 30 to 80 mass %, an average pore diameter of the metallic porous thin plate is in the range of 20 to 800 μm, the metallic porous thin plate has a three-dimensional net-like cell structure, in which a skeleton of the metallic porous thin plate is formed from the metal powder, and a surface shape of a rear surface between the metallic porous thin plate and the main body is asymmetric with respect to a surface shape of a front surface between the metallic porous thin plate and the living tissue, three-dimensionally swollen foamed pores and flatly formed pores being formed on the front surface and rear surface, respectively. |
