Claim 13:
14. A magnetic composite comprising metal magnetic particles and a resin, wherein:
the first metal magnetic particles contain at least one Fe-containing crystalline material; and

(A×Fe content in wt %+B)×α×[log{γ×1/D+δ×(A×Fe content in wt %+B)+ε}]{circumflex over ( )}β≥13,(in wt %)  [Formula 2],, where D is a median diameter of crystallites in μm of the crystalline material, α=14.3, β=−0.67, γ=752, δ=512, ε=−815, A=0.0637, and B=−4.21, and
the Fe constitutes from 91 wt % to 98 wt % of the first metal magnetic particles, and a Si constitutes from 2 wt % to 9 wt % of the first metal magnetic particles.
