Document Type and Number:
Japanese Patent JP2023033192
Kind Code:
A
Abstract:
To provide an electromagnetic wave absorber that, despite its thin thickness, has sufficiently superior electromagnetic wave absorption in at least one of a band of 26.5 to 40 GHz used for 5G radio communication or a band of 74 to 81 GHz used for millimeter wave radar.SOLUTION: An electromagnetic wave absorber contains nanowire (A) and binder (B). The nanowire (A) contains boron and iron. The content of iron with respect to the total of iron, nickel, and boron in the nanowire (A) measured by an ICP-AES method is 65% by mass or more. The content of the nanowire (A) is 85% by mass or less with respect to the nanowire (A) and the binder (B).SELECTED DRAWING: None
