description PROBLEM TO BE SOLVED: To provide a composite magnetic material which provides a compact antenna usable at high frequencies with a wide band and high efficiency, and to provide an antenna, a radio communication apparatus, etc. using the same. SOLUTION: The composite magnetic material has magnetic powder dispersed in an insulating material. The magnetic powder is substantially spherical powder including soft magnetic metal containing ≥97 wt.% Fe and has a mean particle size D50% of 1 to 3 μm and includes a crystallite of 2 to 100 nm in mean crystallite size in a particle. The insulating material is
