The present invention relates to hollow conductive metal particles with softness properties. The hollow conductive particles with softness properties, of the present invention, are metal particles in which, when external pressure is applied thereto, metal particle metal layers do not break and layers of conductive particles with softness properties change according to the surface morphology of objects to which same is applied. The present invention relates to the hollow conductive metal particles and a preparation method therefor.

An amorphous alloy soft magnetic powder includes: impurities; and a composition represented by a composition formula Fe.sub.a(Si.sub.1-xB.sub.x).sub.bC.sub.cS.sub.d represented by an atomic ratio, where a is 100bcd. In addition, b, c, d, and x are 16.0b22.0, 0<c4.0, 0.001d0.080, and 0.5x0.9. In a volume-based cumulative particle size distribution obtained using a laser diffraction type particle size distribution measurement device, when D50 is a particle diameter at which a cumulative frequency is 50% from a small diameter side, the particle diameter D50 is 22.0 m or more and 32.0 m or less, hollow particles are contained, and a number ratio of the hollow particles is 3% or more and 22% or less.
