Abstract

Provided is a composite magnetic material in which low electrical conductivity and high magnetic permeability are achieved, and in which a frequency band in which decoupling is caused encompasses higher frequencies. The composite magnetic material comprises a flat soft magnetic metal powder; insulating particles which are smaller than an average thickness of the soft magnetic metal powder and which are disposed on a surface of the soft magnetic metal powder; and an organic binder material which retains the soft magnetic metal powder and the insulating particles in a dispersed manner. In a cross section in a thickness direction of the soft magnetic metal powder, there is at least one insulating particle per a length of 0.2 μm of the soft magnetic metal powder surface.
