Electromagnetic wave suppressing sheet

An electromagnetic wave suppressing sheet (1) according to the invention is a sheet including a magnetic powder (2) and an insulating material (3). A real part (µ') of a permittivity (µ) in an in-plane direction of the sheet is 200 or more, and an imaginary part (µ") thereof is 25 or more....

Beschreibung
Zusammenfassung:	An electromagnetic wave suppressing sheet (1) according to the invention is a sheet including a magnetic powder (2) and an insulating material (3). A real part (µ') of a permittivity (µ) in an in-plane direction of the sheet is 200 or more, and an imaginary part (µ") thereof is 25 or more. Accordingly, it is possible to obtain the electromagnetic wave absorbing sheet (1) which exhibits an excellent electric wave absorption characteristic in which an absorption amount of electromagnetic waves is large in the in-plane direction of the sheet.
