ELECTROMAGNETIC WAVE ABSORBER, ITS PRODUCING METHOD AND ELECTRONIC APPARATUS |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide an electromagnetic wave absorber exhibiting no directivity in the electromagnetic wave absorbing performance and having a wide application, its producing method and an electronic apparatus comprising the electromagnetic wave absorber. <P>SOLUTION: A first electromagnetic wave absorbing layer 1 and a second electromagnetic wave absorbing layer 2 exhibiting directivity of electromagnetic wave absorption in the plane direction are laid in layer such that the directivity of electromagnetic wave absorption intersects at 90° when viewed from the layer direction thus forming a multilayer electromagnetic wave absorbing layer 5. An electromagnetic wave reflection layer 3 is formed on one side of the multilayer electromagnetic wave absorbing layer 5 and a surface layer 4 is formed on the other side thereof thus constituting a flexible electromagnetic wave absorber 6. <P>COPYRIGHT: (C)2003,JPO |
