Neutron diffraction measurements using single crystal and powder synchrotron X-ray diffraction measurements revealed that an intermediate (I-) phase and a martensite (M-) phase in NiMnGa have incommensurate modulated structures. The modulation vectors of the I- and M-phases are nearly equal to 
= 0.341 at 210 K and = 0.427 at 100 K, respectively. Moreover, displacements of Ni, Mn and Ga atoms in both the I- and M-phase are expressed by sinusoidal waves with the same phase and almost the same amplitudes.
