We prepared the multilayered MgB2 /Ni thin films with the Ni layer spacings of 32, 23 and 16 nm. The MgB2/Ni multilayer nanostructure was confirmed to be obtained from the scanning transmission electron microscope observation. The clear enhancement of Jc was observed in the multilayered MgB2/Ni thin film when the magnetic field was applied parallel to the film surface. Moreover, the peak position of FP - B curves shifted to higher magnetic field with decreasing the Ni layer spacing.
