Provided is a magnetic powder having a high insulation property suitable for a radio wave absorber using a soft magnetic iron alloy. SOLUTION: A composite particle in which soft ferrite particles 2 having an average particle size of 5 μm or less adhere to the surface of soft magnetic iron alloy particles 1 having a particle size of 100 μm or less and an aspect ratio of 5 or more via an organic or inorganic binder 3. A magnetic powder comprising a soft ferrite in a proportion of 40 to 80 parts by mass with respect to 100 parts by mass of a soft magnetic iron alloy. As a soft magnetic iron alloy, Si: 4 to 13% by mass, Al: 4 to 7% by mass, the balance being substantially Fe composition, or Si: 3 to 7% by mass, and the balance being substantially Fe composition Can be suitably used.
