Abstract
A magnetic sheet is used as a noise reduction member for a cable. The magnetic sheet has a width of 5 mm to 15 mm. The magnetic sheet has a magnetic layer and a protective layer. The magnetic layer comprises soft-magnetic particles and a binder. Each of the soft-magnetic particles has a flat shape. A content of the soft-magnetic particles in the magnetic layer is from 35 vol % to 40 vol % with respect to the overall volume of the magnetic layer. The binder is made of polyacrylic rubber or of mixture of polyacrylic rubber and nitrile rubber. The binder binds the soft-magnetic particles to each other. A content of the binder in the magnetic layer is from 35 vol % to 65 vol % with respect to the overall volume of the magnetic layer. The protective layer reinforces the magnetic layer.
