▎ 摘　　要

NOVELTY - Electromagnetic wave absorber comprises a composite material (110) of a sandwich structure in which a surface material (111) is laminated on both sides of a conductive core material (112), where the surface material is a fiber-reinforced plastic, which absorbs electromagnetic waves in both directions simultaneously. USE - The electromagnetic wave absorber is useful for aircraft doors. ADVANTAGE - The electromagnetic wave absorber has excellent electromagnetic wave absorption ability, high mechanical strength, and simultaneously absorbs electromagnetic waves in both directions. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the electromagnetic wave absorber. 110Composite material 111Surface material 112Conductive core material 122Protective layer
