Abstract
A soft magnetic metal powder or the like from which a soft magnetic metal fired body can be provided has a high magnetic permeability μ and a specific resistance ρ and is contained in a coil-type electronic component having sufficiently high inductance L and Q value and unlikely to be plating-extended and short-circuited. A soft magnetic metal powder contains soft magnetic metal particles containing at least Fe and Ni. Said soft magnetic metal powder further contains P, Si, Cr and/or M. M is at least one selected from among B, Co, Mn, Ti, Zr, Hf, Nb, Ta, Mo, Mg, Ca, Sr, Ba, Zn, Al, and rare earth elements. The content of each element is within a predetermined range.
