A Ni-Fe based alloy powder of the present invention contains not less than 90% by a combined mass of Ni and Fe and homogeneously has particles having an average particle diameter from 0.1 to 1 mu m, and an average value of mass ratio Fe/ (Fe + Ni) from 15% to 25% both inclusive, wherein the ratio of a maximum value X and a minimum value Y of Fe/ (Fe + Ni), which are found at individual points in the region ranging from the center of any particle of the alloy powder to locations apart by 0. 9 fold of the particle radius therefrom, X/Y is from 1 to 2. By producing a sintered part using this Ni-Fe based alloy powder as a raw material powder, it is possible to obtain electronic circuit parts which are homogenous and have high magnetic permeability. <IMAGE> |
