Provided is an alloy powder of the compositional formula Fe100-a-b-c-d-e-fCoaBbSicPdCueCf, having an amorphous phase as the principal phase. When the parameters of the composition satisfy the conditions: 3.5 ≦ a ≦ 4.5 at%; 6 ≦ b ≦ 15 at%; 2 ≦ c ≦ 11 at%; 3 ≦ d ≦ 5 at%; 0.5 ≦ e ≦ 1.1 at%; and 0 ≦ f ≦ 2 at%, the material has good magnetic characteristics even when the powder has a large particle diameter of 90 μm, and therefore the yield is improved. |
