Abstract:
To provide a magnetic sheet suitable for a noise counterplan for a cable.SOLUTION: A magnetic sheet 10 is used as noise counterplan means for a cable. The magnetic sheet 10's width is 5 to 15 mm. The magnetic sheet 10 comprises a magnetic layer 100 and a protective layer 300. The magnetic layer 100 includes soft magnetic material powder 110 and a binder 120. The soft magnetic material powder 110 has a flat shape. The ratio of the soft magnetic material powder 110 in the magnetic layer 100 is 35 to 40% by volume with respect to the whole volume of the magnetic layer 100. The binder 120 is acryl rubber or a mixture of acryl rubber and nitrile rubber. The binder 120 binds the soft magnetic material powder 110. The ratio of the binder 120 in the magnetic layer 100 is 35 to 65% by volume with respect to the whole volume of the magnetic layer 100.
