摘要：
A component for suppressing EMI includes a composite magnetic material layer and a composite permanent magnet layer disposed on at least part of the composite magnetic material layer. In the component, the composite magnetic material layer contains an organic binder and a soft magnetic material powder dispersed in the organic binder. The composite permanent magnet layer contains a binder and a permanent magnet powder dispersed in the binder. A bias magnetic field is applied to the composite magnetic material layer from the composite permanent magnet layer.
