| 摘要 |
<p>The present invention is a radio wave absorber having a high absorption performance for an electromagnetic wave of a high frequency and made thinner. The radio wave absorber comprises one or more magnetic layers including a magnetic material having a micro organization structure whose particle diameter is controlled to 1 to 100 nm. A radio wave absorbing sheet (2) comprises one magnetic layer formed by preparing as such a magnetic material including Fe, Co and Ni, which are ferromagnetic elements, or a material including an alloy containing Mn, as powder, and dispersing this powder into polymeric material and the like, and it has a radio wave absorption performance for a relatively near electromagnetic field. <IMAGE></p> |
