Document Type and Number:
Japanese Patent JP7299189
Kind Code:
B2
Abstract:
[Problem] To provide an electromagnetic wave absorption member that absorbs unnecessary electromagnetic waves. [Solution] An electromagnetic wave absorption member provided in the vicinity of a radar device using millimeter waves or submillimeter waves comprises a first region, and a second region in a position differing from the first region. Both the first region and the second region include a metal mesh pattern, a resin layer, and a metal layer in the stated order from an inner-surface side positioned on the radar-device side to an outer-surface side. The occupancy of the metal mesh pattern in the first region differs from the occupancy of the metal mesh pattern in the second region.
