Abstract
A high-frequency core 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 a general formula (FeNiCo)(MM')TB(where 0≦a≦0.30, 0≦b≦0.50, 0≦a+b≦0.50, 0≦p≦0.5, 1 atomic %≦x≦5 atomic %, 1 atomic %≦y≦12 atomic %, 12 atomic %≦z≦25 atomic %, 22≦(x+y+z)≦32, 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, R (R being at least one element selected from rare earth metals including Y), T being at least one selected from Al, Si, C, and P). An inductance component includes the high-frequency core and at least one turn of winding wound around the core.
