This research, it is the purpose to design and verify a new composite actuator material of the magnetic field drive which has large displacement and high intensity because it is composite of magnetostriction material and a superelastic alloy. Component material chose titanium nickel (TiNi) as the shape memory alloy (SMA), and chose nickel (Ni) as magnetostriction material. The Spark Plasma Sintering (SPS) method was used for composite. Moreover, two kinds of volume ratios of a composite material were chosen. Cross section observation, compression test, and magnetostriction measurement were performed for verification of the characteristic. As a result of magnetostriction measurement, the -57ppm (-40ppm with nickel) magnetostriction was measured by the composite material, and the increase in the maximum magnetostriction was checked.
