Abstract
A composite magnetic material contains first magnetic particles made of a first magnetic material and second magnetic particles made of a second magnetic material, the first and second magnetic particles being mixed with each other. A frequency characteristic of the first magnetic material is different from that of the second magnetic material. The first and second magnetic particles are mixed so that, at a frequency of an intersecting point between a first curve representing a frequency characteristic of a real part of a complex magnetic permeability of the first magnetic material and a second curve representing a frequency characteristic of a real part of a complex magnetic permeability of the second magnetic material, a value of a real part of a complex magnetic permeability of the composite magnetic material is larger than a value of the intersecting point.
