PROBLEM TO BE SOLVED: To provide a radio wave absorber matched to a frequency band of several hundreds of MHz to several tens of GHz in which flexibility and good kneadability, dispersibility and moldability are satisfied while keeping good reflection attenuation characteristics. SOLUTION: In the radio wave absorber where metallic soft magnetic particles having an insulation coating on the surface are dispersed into an organic polymer, the insulation coating comprises an organic compound having an alkyl group of 6-25C. More preferably, the insulation coating comprises a molecule having any functional group selected from silane based hydrolyzable group, carboxyl group, hydroxy group, and phosphate group at one terminal of an organic compound. |
