Abstract
(EN)
Provided is a radio wave-absorbing composition containing a magnetic powder and a binder. Also provided is a radio wave-absorbing body containing a magnetic powder and a binder. The magnetic powder is a powder of a substituted-type hexagonal ferrite surface treated by a surface treatment agent. The surface treatment agent is a silicon compound, and the binder is an olefin resin.
