Abstract (en)
A high-frequency core (1) is a molded body obtained by molding a mixture of a soft magnetic metallic glass powder and a binder in an amount of 10% or less in mass ratio. The powder has an alloy composition represented by (Fe1-aCoa)100-x-y-z-q-r(M1-pM'p)xTyBzCqAlr (0 < a < 0.50, 0 < p < 0.5, 2 atomic% < x < 5 atomic%, 8 atomic% < y < 12 atomic%, 12 atomic% < z < 17 atomic%, 0.1 atomic% < q < 1.0 atomic%, 0.2 atomic% < r < 2.0 atomic% and 25 < (x+y+z+q+r) < 30, M being at least one selected from Zr, Nb, Ta, Hf, Mo, Ti, V, Cr, and W, M' being at least one selected from Zn, Sn, and R (R being at least one element selected from rare earth metals including Y), T being at least one selected from Si and P). An inductance component (101, 102) is formed by the core and a winding (3). <IMAGE>
