Title:
RADIO WAVE SUPPRESSION SHEET, AND ELECTRONIC APPARATUS AND RADIO WAVE SUPPRESSION COMPONENT EQUIPPED WITH THIS SHEET
Document Type and Number:
Japanese Patent JP2012204734
Kind Code:
A
Abstract:

To provide a radio wave suppression sheet which can exhibit excellent radio wave absorbing performance and radio wave shielding performance, and to provide an electronic apparatus and a radio wave suppression component equipped with the radio wave suppression sheet.

Carbon nanotubes are dispersed into silicone rubber and the silicone rubber is molded into film-shape having a thickness of 300 μm or less. The content of the carbon nanotubes is preferably 15 mass% or more. The radio wave suppression sheet has a part where the transmission attenuation factor for microwaves having a frequency of 5.0 GHz or lower measured by microstrip method is 40 dB or higher. An electronic apparatus and a radio wave suppression component equipped with this sheet are also provided.
