ELECTROMAGNETIC WAVE ATTENUATION BODY AND ELECTRONIC DEVICE

Japanese Patent JP2023070230

A

To provide an electromagnetic wave attenuation body that can increase the attenuation characteristics of an electromagnetic wave and an electronic device.SOLUTION: The electromagnetic wave attenuation body according to an embodiment includes a laminate member including a first sheet part. The first planer part includes a first laminate body. The first laminate body includes a plurality of first magnetic layers and a plurality of first non-magnetic layers containing Cr and Ti. The direction from first one of the first magnetic layers to second one of the first magnetic layers extend along a first direction. One of the first non-magnetic layers is located between the first one of the magnetic layers and the second one of the first magnetic layers. The first one of the first non-magnetic layers includes an amorphous region. The first one of the first magnetic layers and the second one of the first magnetic layers include a crystal region.SELECTED DRAWING: Figure 1
