PURPOSE: A biomaterial for MRI(Magnetic Resonance Imaging) diagnosis and a method of manufacturing the same are provided to relieve distortion of an image when a body is operated, diagnosed, or analyzed using an MRI. CONSTITUTION: A biomaterial for MRI diagnosis comprises at least one diamagnetic substance selected from a group consisting of a carbonaceous material and bismuth; and at least one paramagnetic substance selected from a group consisting of nitinol, niobium, titanium, and zirconium. The diamagnetic substance comprises a carbonaceous material. The carbonaceous material is graphite. The paramagnetic material comprises titanium. The amount of titanium is 70-90 vol%.
