Claim 0:
1. A nitinol nanofiber made of an alloy of nickel and titanium, wherein the nitinol nanofiber has a nanofiber shape having a largest diameter in a range of 10 nm to 1,000, has a surface roughness formed over an area of 10% to 30% of the entire surface of the nitinol nanofiber, has an average roughness in a range of 0.5 nm to 40 nm, and has a roughness-formed region in which a height difference between top and bottom is in a range of 0.01 to 80 nm,
wherein the nitinol nanofiber comprises a metal oxide surface layer on a surface thereof, and
wherein the metal oxide surface layer contains 10 to 30 at.% of nickel, 10 to 50 at.% of titanium, 25 to 70 at.% of oxygen, and a total of 10 to 35 at.% of one or more elements selected from the group consisting of Mo, Fe, Al, C, and N.
