Title:
ELECTROMAGNETIC WAVE ABSORPTION SHEET
Document Type and Number:
WIPO Patent Application WO/2018/084235
Kind Code:
A1
Abstract:
To realize an electromagnetic wave absorption sheet that is capable of satisfactorily absorbing electromagnetic waves having high frequencies in and above the millimeter wave band, and that exhibits elasticity of stretching in the planar direction. An electromagnetic wave absorption sheet having an electromagnetic wave absorption layer 1 containing a rubber binder 1b and a magnetic iron oxide 1a, which is an electromagnetic wave-absorbing material that magnetically resonates in a frequency band in and above the millimeter wave band, wherein the maximum elongation ratio of the elastic region of the electromagnetic wave absorption sheet in one in-plane direction is 20-200%.
