PROBLEM TO BE SOLVED: To provide Fe-Ni-Mo based flat metal soft magnetic powder, and to provide Fe-Ni-Mo based oxide film-coated flat metal soft magnetic powder with an oxide film formed on the surface of the same powder.;SOLUTION: The flat metal soft magnetic powder has a composition containing 60 to 90% Ni, 0.05 to 10% Mo and one or more selected from Nb, V and Ta by 0.05 to 19.95% in total, and, if required, one or two selected from Al and Mn by 0.01 to 1% in total, and the balance Fe, and has dimensions and shape satisfying the average particle diameter of 30 to 150 μm and an aspect ratio of 5 to 500, wherein when the peak height of the plane index (220) in the X-ray diffraction pattern measured in such a manner that the plane including the incidence direction and diffraction direction of X-rays is made vertical to the flat plane of the flat metal soft magnetic powder, and also, the angle formed by the incidence direction and the flat plane and the angle formed by the diffraction direction and the flat plane are made equal, is denoted as I220 and the peak height of the plane index (111) is denoted as I111, the peak intensity ratio I220/I111 is within the range of 0.1 to 10.;COPYRIGHT: (C)2006,JPO&NCIPI
