Title:
ELECTROMAGNETIC WAVE ABSORBING LAMINATE, CASE AND METHOD FOR USING ELECTROMAGNETIC WAVE ABSORBING LAMINATE
Document Type and Number:
WIPO Patent Application WO/2017/082318
Kind Code:
A1
Abstract:
An electromagnetic wave absorbing laminate which is used for the purpose of covering the surface of an electronic device, and which comprises: a magnetic material layer that is formed from a first resin material containing a thermosetting resin and particles and/or fibers configured from a magnetic metal; and a conductive material layer that is formed from a second resin material containing a thermosetting resin and a conductive material. If Ra is the electromagnetic wave reflection amount of the magnetic material layer and Rb is the electromagnetic wave reflection amount of the conductive material layer, Ra and Rb satisfy Ra ≤ Rb. In addition, it is preferable that the magnetic material layer is configured of a body that is made through a papermaking process and contains the first resin material; and it is also preferable that the conductive material layer is configured of a body that is made through a papermaking process and contains the second resin material.
